Description
The TS97x family of operational amplifiers operates with voltages as low as 1.35V and features output rail-to-rail signal swing. The TS97x are particularly well suited for portable and battery-supplied equipment. Very low noise and low distortion characteristics make them ideal for audio pre-amplification. The TS971 is available in a variety of packages to suit all types of applications. For applications where space-saving is critical, the SOT23 package (2.8 x 2.9mm) or the DFN package (3 x 3mm) simplify the board design because they can be placed everywhere.

1. 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. 3. The magnitude of input and output voltages must never exceed VCC +0.3V. 4. Short-circuits can cause excessive heating and destructive dissipation. Values are typical. 5. Human body model: A 100pF 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 200pF 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. No value specified for CDM on SOT23-5 package.
