description
The TLC0820AC and the TLC0820AI are
Advanced LinCMOS 8-bit analog-to-digital
converters each consisting of two 4-bit flash
converters, a 4-bit digital-to-analog converter, a
summing (error) amplifier, control logic, and a
result latch circuit. The modified flash technique
allows low-power integrated circuitry to complete
an 8-bit conversion in 1.18 µs over temperature.
The on-chip track-and-hold circuit has a 100-ns
sample window and allows these devices to
convert continuous analog signals having slew
rates of up to 100 mV/µs without external
sampling components. TTL-compatible 3-state
output drivers and two modes of operation allow
interfacing to a variety of microprocessors. Detailed information on interfacing to most popular microprocessors
is readily available from the factory.

D7 17 O Digital, 3-state output data, bit 8 (MSB)
GND 10 Ground
INT 9 O Interrupt. In the write-read mode, the interrupt output (INT) going low indicates that the internal count-down delay
time, td(int), is complete and the data result is in the output latch. The delay time td(int) is typically 800 ns starting
after the rising edge of WR (see operating characteristics and Figure 3). If RD goes low prior to the end of td(int),
INT goes low at the end of td(RIL) and the conversion results are available sooner (see Figure 2). INT is reset by
the rising edge of either RD or CS.
MODE 7 I Mode select. MODE is internally tied to GND through a 50-µA current source, which acts like a pulldown resistor .
When MODE is low, the read mode is selected. When MODE is high, the write-read mode is selected.
NC 19 No internal connection
OFLW 18 O Overflow . Normally OFL W is a logical high. However , if the analog input is higher than V ref+, OFL W will be low at
the end of conversion. It can be used to cascade two or more devices to improve resolution (9 or 10 bits).
RD 8 I Read. In the write-read mode with CS low, the 3-state data outputs D0 through D7 are activated when RD goes
low. RD can also be used to increase the conversion speed by reading data prior to the end of the internal
count-down delay time. As a result, the data transferred to the output latch is latched after the falling edge of RD.
In the read mode with CS low , the conversion starts with RD going low . RD also enables the 3-state data outputs
on completion of the conversion. RDY going into the high-impedance state and INT going low indicate completion
of the conversion.
REF– 11 I Reference voltage. REF– is placed on the bottom of the resistor ladder.
REF+ 12 I Reference voltage. REF+ is placed on the top of the resistor ladder.
VCC 20 Power supply voltage
WR/RDY 6 I/O Write ready. In the write-read mode with CS low, the conversion is started on the falling edge of the WR input signal.
The result of the conversion is strobed into the output latch after the internal count-down delay time, td(int), provided
that the RD input does not go low prior to this time. The delay time td(int) is approximately 800 ns. In the read mode,
RDY (an open-drain output) goes low after the falling edge of CS and goes into the high-impedance state when
the conversion is strobed into the output latch. It is used to simplify the interface to a microprocessor system.

PRINCIPLES OF OPERATION
The TLC0820AC and TLC0820AI each employ a combination of sampled-data comparator techniques and flash
techniques common to many high-speed converters. Two 4-bit flash analog-to-digital conversions are used to give
a full 8-bit output.
The recommended analog input voltage range for conversion is –0.1 V to VCC + 0.1 V. Analog input signals that are
less than Vref– + 1/2 LSB or greater than Vref+ – 1/2 LSB convert to 00000000 or 11111111, respectively. The reference
inputs are fully differential with common-mode limits defined by the supply rails. The reference input values define
the full-scale range of the analog input. This allows the gain of the ADC to be varied for ratiometric conversion by
changing the Vref+ and V ref– voltages.
The device operates in two modes, read (only) and write-read, that are selected by MODE. The converter is set to
the read (only) mode when MODE is low. In the read mode, WR/RDY is used as an output and is referred to as the
ready terminal. In this mode, a low on WR/RDY while CS is low indicates that the device is busy. Conversion starts
on the falling edge of RD and is completed no more than 2.5 µs later when INT falls and WR/RDY returns to the
high-impedance state. Data outputs also change from high-impedance to active states at this time. After the data is
read, RD is taken high, INT returns high, and the data outputs return to their high-impedance states.
When MODE is high, the converter is set to the write-read mode and WR/RDY is referred to as the write terminal.
Taking CS and WR/RDY low selects the converter and initiates measurement of the input signal. Approximately
600 ns after WR/RDY returns high, the conversion is completed. Conversion starts on the rising edge of WR/RDY
in the write-read mode.
The high-order 4-bit flash ADC measures the input by means of 16 comparators operating simultaneously. A
high-precision 4-bit DAC then generates a discrete analog voltage from the result of that conversion. After a time
delay, a second bank of comparators does a low-order conversion on the analog difference between the input level
and the high-order DAC output. The results from each of these conversions enter an 8-bit latch and are output to the
3-state output buffers on the falling edge of RD.

TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should
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.
