DESCRIPTION
The DAC8532 is a dual channel, 16-bit Digital-to-Analog
Converter (DAC) offering low power operation and a flexible
serial host interface. Each on-chip precision output amplifier
allows rail-to-rail output swing to be achieved over the supply
range of 2.7V to 5.5V. The device supports a standard 3-wire
serial interface capable of operating with input data clock
frequencies up to 30MHz for VDD = 5V.
The DAC8532 requires an external reference voltage to set
the output range of each DAC channel. Also incorporated
into the device is a power-on reset circuit which ensures that
the DAC outputs power up at zero-scale and remain there
until a valid write takes place. The DAC8532 provides a
flexible power-down feature, accessed over the serial inter-
face, that reduces the current consumption of the device to
200nA at 5V.
The low-power consumption of this device in normal opera-
tion makes it ideally suited to portable battery-operated
equipment and other low-power applications. The power
consumption is 2.5mW at 5V, reducing to 1µW in power-
down mode.
The DAC8532 is available in a MSOP-8 package with a
specified operating temperature range of –40°C to +105°C.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.

3V
OUTB Analog output voltage from DAC B.
4V
OUTA Analog output voltage from DAC A.
5 SYNC Level triggered SYNC input (active LOW). This is the
frame synchronization signal for the input data.
When SYNC goes LOW, it enables the input shift
register and data is transferred on the falling edge of
SCLK. The action specified by the 8-bit control byte
and 16-bit data word is executed following the 24th
falling SCLK clock edge (unless SYNC is taken
HIGH before this edge in which case the rising edge
of SYNC acts as an interrupt and the write sequence
is ignored by the DAC8532).
6 SCLK Serial Clock Input. Data can be transferred at rates
up to 30 MHz at 5V.
7D
IN Serial Data Input. Data is clocked into the 24-bit
input shift register on each falling edge of the serial
clock input.
8 GND Ground reference point for all circuitry on the part.

THEORY OF OPERATION
DAC SECTION
The architecture of each channel of the DAC8532 consists of
a resistor string DAC followed by an output buffer amplifier.
Figure 1 shows a simplified block diagram of the DAC
architecture.
The input coding for each device is unipolar straight binary,
so the ideal output voltage is given by:
VXV D
OUT REF
=•
65536
where D = decimal equivalent of the binary code that is
loaded to the DAC register; it can range from 0 to 65535.
VOUTX refers to channel A or B.
RESISTOR STRING
The resistor string section is shown in Figure 2. It is simply
a divide-by-2 resistor followed by a string of resistors, each
of value R. The code loaded into the DAC register deter-
mines at which node on the string the voltage is tapped off.
This voltage is then applied to the output amplifier by closing
one of the switches connecting the string to the amplifier.
OUTPUT AMPLIFIER
Each output buffer amplifier is capable of generating rail-to-
rail voltages on its output which approaches an output range
of 0V to VDD (gain and offset errors must be taken into
account). Each buffer is capable of driving a load of 2k in
parallel with 1000pF to GND. The source and sink capabili-
ties of the output amplifier can be seen in the typical charac-
teristics.
SERIAL INTERFACE
The DAC8532 uses a 3-wire serial interface (SYNC, SCLK,
and DIN), which is compatible with SPI, QSPI, and
Microwire interface standards, as well as most DSPs. See
the Serial Write Operation timing diagram for an example of
a typical write sequence.

The write sequence begins by bringing the SYNC line LOW.
Data from the DIN line is clocked into the 24-bit shift register
on each falling edge of SCLK. The serial clock frequency can
be as high as 30MHz, making the DAC8532 compatible with
high speed DSPs. On the 24th falling edge of the serial clock,
the last data bit is clocked into the shift register and the
programmed function is executed (i.e., a change in Data
Buffer contents, DAC Register contents, and/or a change in
the power-down mode of a specified channel or channels).
At this point, the SYNC line may be kept LOW or brought
HIGH. In either case, the minimum delay time from the 24th
falling SCLK edge to the next falling SYNC edge must be met
in order to properly begin the next cycle. To assure the
lowest power consumption of the device, care should be
taken that the digital input levels are as close to each rail as
possible. (Please refer to the Typical Characteristics sec-
tion for the Supply Current vs Logic Input Voltage transfer
characteristic curve).

INPUT SHIFT REGISTER
The input shift register of the DAC8532 is 24 bits wide (see
Figure 5) and is made up of 8 control bits (DB16-DB23) and 16
data bits (DB0-DB15). The first two control bits (DB22 and
DB23) are reserved and must be 0 for proper operation. LD
A (DB20) and LD B (DB21) control the updating of each analog
output with the specified 16-bit data value or power-down
command. Bit DB19 is a Don't Care bit which does not affect
the operation of the DAC8532 and can be 1 or 0. The following
control bit, Buffer Select (DB18), controls the destination of the
data (or power-down command) between DAC A and DAC B.
The final two control bits, PD0 (DB16) and PD1 (DB17), select
the power-down mode of one or both of the DAC channels. The
four modes are normal mode or any one of three power-down
modes. A more complete description of the operational modes
of the DAC8532 can be found in the Power-Down Modes
section. The remaining sixteen bits of the 24-bit input word
make up the data bits. These are transferred to the specified
Data Buffer or DAC Register, depending on the command
issued by the control byte, on the 24th falling edge of SCLK.
Please refer to Tables II and III for more information.
are set to zero-scale; they remain there until a valid write
sequence and load command is made to the respective
DAC channel. This is useful in applications where it is
important to know the state of the output of each DAC
output while the device is in the process of powering up.
No device pin should be brought high before power is
applied to the device.
POWER-DOWN MODES
The DAC8532 utilizes four modes of operation. These modes
are accessed by setting two bits (PD1 and PD0) in the control
register and performing a Load action to one or both DACs.
Table I shows how the state of the bits correspond to the
mode of operation of each channel of the device. (Each DAC
channel can be powered down simultaneously or indepen-
dently of each other. Power-down occurs after proper data is
written into PD0 and PD1 and a Load command occurs.)

tional information.

FIGURE 3. Output Stage During Power-Down (High-Impedance)
SYNC INTERRUPT
In a normal write sequence, the SYNC line is kept LOW for
at least 24 falling edges of SCLK and the addressed DAC
register is updated on the 24th falling edge. However, if
SYNC is brought HIGH before the 24th falling edge, it acts as
an interrupt to the write sequence; the shift register is reset
and the write sequence is discarded. Neither an update of
the data buffer contents, DAC register contents or a change
in the operating mode occurs (see Figure 4).
POWER-ON RESET
The DAC8532 contains a power-on reset circuit that con-
trols the output voltage during power-up. On power-up, the
DAC registers are filled with zeros and the output voltages

TABLE I. Modes of Operation for the DAC8532.
When both bits are set to 0, the device works normally with
a typical power consumption of 500µA at 5V. For the three
power-down modes, however, the supply current falls to
200nA at 5V (50nA at 3V). Not only does the supply current
fall but the output stage is also internally switched from the
output of the amplifier to a resistor network of known values.
This has the advantage that the output impedance of the
device is known while it is in power-down mode. There are
three different options for power-down: The output is con-
nected internally to GND through a 1k resistor, a 100k
resistor, or it is left open-circuited (High-Impedance). The
output stage is illustrated in Figure 3.
All analog circuitry is shut down when the power-down mode
is activated. Each DAC will exit power-down when PD0 and
PD1 are set to 0, new data is written to the Data Buffer, and
the DAC channel receives a Load command. The time to
exit power-down is typically 2.5µs for VDD = 5V and 5µs for
VDD = 3V (See the Typical Characteristics).

DAC8532 to Microwire INTERFACE
Figure 7 shows an interface between the DAC8532 and any
Microwire compatible device. Serial data is shifted out on the
falling edge of the serial clock and is clocked into the
DAC8532 on the rising edge of the SK signal.
MICROPROCESSOR
INTERFACING
DAC8532 to 8051 INTERFACE
Figure 6 shows a serial interface between the DAC8532 and
a typical 8051-type microcontroller. The setup for the inter-
face is as follows: TXD of the 8051 drives SCLK of the
DAC8532, while RXD drives the serial data line of the device.
The SYNC signal is derived from a bit-programmable pin on
the port of the 8051. In this case, port line P3.3 is used. When
data is to be transmitted to the DAC8532, P3.3 is taken LOW.
The 8051 transmits data in 8-bit bytes; thus only eight falling
clock edges occur in the transmit cycle. To load data to the
DAC, P3.3 is left LOW after the first eight bits are transmitted,
then a second and third write cycle is initiated to transmit the
remaining data. P3.3 is taken HIGH following the completion
of the third write cycle. The 8051 outputs the serial data in a
format which presents the LSB first, while the DAC8532
requires its data with the MSB as the first bit received. The
8051 transmit routine must therefore take this into account,
and mirror the data as needed.
The 68HC11 should be configured so that its CPOL bit is 0
and its CPHA bit is 1. This configuration causes data appear-
ing on the MOSI output to be valid on the falling edge of SCK.
When data is being transmitted to the DAC, the SYNC line is
held LOW (PC7). Serial data from the 68HC11 is transmitted
in 8-bit bytes with only eight falling clock edges occurring in
the transmit cycle. (Data is transmitted MSB first.) In order to
load data to the DAC8532, PC7 is left LOW after the first
eight bits are transferred, then a second and third serial write
operation is performed to the DAC. PC7 is taken HIGH at the
end of this procedure.
DAC8532 to TMS320 DSP INTERFACE
Figure 9 shows the connections between the DAC8532 and
a TMS320 digital signal processor. By decoding the FSX
signal, multiple DAC8532s can be connected to a single
serial port of the DSP.

Figure 8 shows a serial interface between the DAC8532 and
the 68HC11 microcontroller. SCK of the 68HC11 drives the
SCLK of the DAC8532, while the MOSI output drives the
serial data line of the DAC. The SYNC signal is derived from
a port line (PC7), similar to the 8051 diagram.

APPLICATIONS
CURRENT CONSUMPTION
The DAC8532 typically consumes 250uA at VDD = 5V and
225uA at VDD = 3V for each active channel, including refer-
ence current consumption. Additional current consumption
can occur at the digital inputs if VIH<<VDD. For most efficient
power operation, CMOS logic levels are recommended at the
digital inputs to the DAC.
In power-down mode, typical current consumption is 200nA.
A delay time of 10 to 20ms after a power-down command is
issued to the DAC is typically sufficient for the power-down
current to drop below 10µA.

DRIVING RESISTIVE AND CAPACITIVE LOADS
The DAC8532 output stage is capable of driving loads of up
to 1000pF while remaining stable. Within the offset and gain
error margins, the DAC8532 can operate rail-to-rail when
driving a capacitive load. Resistive loads of 2k can be
driven by the DAC8532 while achieving a typical load regu-
lation of 1%. As the load resistance drops below 2k, the
load regulation error increases. When the outputs of the DAC
are driven to the positive rail under resistive loading, the
PMOS transistor of each Class-AB output stage can enter
into the linear region. When this occurs, the added IR voltage
drop deteriorates the linearity performance of the DAC. This
only occurs within approximately the top 20mV of the DACs
digital input-to-voltage output transfer characteristic. The
reference voltage applied to the DAC8532 may be reduced
below the supply voltage applied to VDD in order to eliminate
this condition if good linearity is a requirement at full scale
(under resistive loading conditions).
CROSSTALK AND AC PERFORMANCE
The DAC8532 architecture uses separate resistor strings for
each DAC channel in order to achieve ultra-low crosstalk
performance. DC crosstalk seen at one channel during a full-
scale change on the neighboring channel is typically less than
0.5LSBs. The AC crosstalk measured (for a full-scale, 1kHz
sine wave output generated at one channel, and measured at
the remaining output channel) is typically under 100dB.
In addition, the DAC8532 can achieve typical AC perfor-
mance of 96dB SNR (Signal-to-Noise Ratio) and 65db THD
(Total Harmonic Distortion), making the DAC8532 a solid
choice for applications requiring low SNR at output frequen-
cies at or below 4kHz.
OUTPUT VOLTAGE STABILITY
The DAC8532 exhibits excellent temperature stability of
5ppm/°C typical output voltage drift over the specified tem-
perature range of the device. This enables the output voltage
of each channel to stay within a ±25µV window for a ±1°C
ambient temperature change.
Good Power-Supply Rejection Ratio (PSRR) performance
reduces supply noise present on VDD from appearing at the
outputs to well below 10µV-s. Combined with good DC noise
performance and true 16-bit differential linearity, the DAC8532
becomes a perfect choice for closed-loop control applica-
tions.
SETTLING TIME AND OUTPUT
GLITCH PERFORMANCE
Settling time to within the 16-bit accurate range of the
DAC8532 is achievable within 10µs for a full-scale code
change at the input. Worst case settling times between
consecutive code changes is typically less than 2µs, en-
abling update rates up to 500ksps for digital input signals
changing code-to-code. The high-speed serial interface of
the DAC8532 is designed in order to support these high
update rates.
For full-scale output swings, the output stage of each
DAC8532 channel typically exhibits less than 100mV of
overshoot and undershoot when driving a 200pF capacitive
load. Code-to-code change glitches are extremely low
(~10uV) given that the code-to-code transition does not
cross an Nx4096 code boundary. Due to internal segmen-
tation of the DAC8532, code-to-code glitches occur at each
crossing of an Nx4096 code boundary. These glitches can
approach 100mVs for N = 15, but settle out within ~2µs.
USING REF02 AS A POWER SUPPLY FOR DAC8532
Due to the extremely low supply current required by the
DAC8532, a possible configuration is to use a REF02 +5V
precision voltage reference to supply the required voltage to
the DAC8532's supply input as well as the reference input, as
shown in Figure 10. This is especially useful if the power
supply is quite noisy or if the system supply voltages are at
some value other than 5V. The REF02 will output a steady
supply voltage for the DAC8532. If the REF02 is used, the
current it needs to supply to the DAC8532 is 567µA typical
and 890µA max for VDD = 5V. When a DAC output is loaded,
the REF02 also needs to supply the current to the load. The
total typical current required (with a 5k load on a given DAC
output) is:
567µA + (5V/5k) = 1.567mA

The load regulation of the REF02 is typically 0.005%/mA,
which results in an error of 392µV for the 1.5mA current
drawn from it. This corresponds to a 5.13LSB error for a 0V
to 5V output range.
BIPOLAR OPERATION USING THE DAC8532
The DAC8532 has been designed for single-supply opera-
tion but a bipolar output range is also possible using the
circuit in Figure 11. The circuit shown will give an output
voltage range of ±VREF. Rail-to-rail operation at the amplifier
output is achievable using an amplifier such as the OPA703,
see Figure 11.

range can be achieved.
LAYOUT
A precision analog component requires careful layout, ad-
equate bypassing, and clean, well-regulated power supplies.
The DAC8532 offers single-supply operation, and it will often
be used in close proximity with digital logic, microcontrollers,
microprocessors, and digital signal processors. The more
digital logic present in the design and the higher the switch-
ing speed, the more difficult it will be to keep digital noise
from appearing at the output.

Due to the single ground pin of the DAC8532, all return
currents, including digital and analog return currents for the
DAC, must flow through a single point. Ideally, GND would
be connected directly to an analog ground plane. This plane
would be separate from the ground connection for the digital
components until they were connected at the power entry
point of the system.
The power applied to VDD should be well regulated and low
noise. Switching power supplies and DC/DC converters will
often have high-frequency glitches or spikes riding on the
output voltage. In addition, digital components can create
similar high-frequency spikes as their internal logic switches
states. This noise can easily couple into the DAC output
voltage through various paths between the power connec-
tions and analog output.
As with the GND connection, VDD should be connected to a
positive power-supply plane or trace that is separate from the
connection for digital logic until they are connected at the
power entry point. In addition, a 1µF to 10µF capacitor in
parallel with a 0.1µF bypass capacitor is strongly recom-
mended. In some situations, additional bypassing may be
required, such as a 100µF electrolytic capacitor or even a
Pi filter made up of inductors and capacitorsall designed
to essentially low-pass filter the supply, removing the high-
frequency noise.

obtain the latest relevant information before placing orders and should verify that such information is current and complete. All
semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time
of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
