TS922, TS922A Rail-to-rail high output current dual operational amplifier Features Rail-to-rail input and output Low noise: 9 nV/ Hz Low distortion High output current: 80 mA (able to drive 32 loads) High-speed: 4 MHz, 1 V/s Operating from 2.7 to 12 V Low input offset voltage: 900 V max (TS922A) ESD internal protection: 2 kV Latch-up immunity Macromodel included in this specification Dual version available in flip-chip package J (Flip-chip) D SO-8 (Plastic micropackage) P TSSOP8 (Thin shrink small outline package) Applications Headphone amplifiers Sound cards, multimedia systems Line drivers, actuator drivers Servo amplifiers Mobile phones and portable equipment Instrumentation with low noise as key factor Piezoelectric speaker drivers N DIP8 (Plastic package) The device is stable for capacitive loads up to 500 pF. Description The TS922 is a rail-to-rail dual BiCMOS operational amplifier optimized and fully specified for 3 and 5 V operation. The device's high output current allows low-load impedances to be driven. Very low noise, low distortion, low offset and a high output current capability make this device an excellent choice for high quality, low voltage or battery operated audio systems.

All voltage values, except differential voltage are with respect to network ground terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. If Vid > 1 V, the maximum input current must not exceed 1 mA. In this case (Vid > 1 V), an input series resistor must be added to limit the input current. 3. Do not exceed 14 V. 4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous shortcircuits on all amplifiers. These values are typical. 5. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5k resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 6. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 ). This is done for all couples of connected pin combinations while the other pins are floating. 7. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. 8. There is no short-circuit protection inside the device: short-circuits from the output to VCC can cause excessive heating. The maximum output current is approximately 80 mA, independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuits on all amplifiers.

Macromodels are not a substitute to breadboarding; rather, they confirm the validity of a design approach and help to select surrounding component values. A macromodel emulates the nominal performance of a typical device within specified operating conditions (temperature, supply voltage, for example). Thus the macromodel is often not as exhaustive as the datasheet, its purpose is to illustrate the main parameters of the product. Data derived from macromodels used outside of the specified conditions (VCC, temperature, for example) or even worse, outside of the device operating conditions (VCC, Vicm, for example), is not reliable in any way. Section 4.2 provides the electrical characteristics resulting from the use of this macromodel. 4.2 Electrical characteristics from macromodelization Table 5.
