DESCRIPTION
The TS97x family operational amplifiers is able to
operate with voltages as low as ±1.35V and featur-
ing output Rail to Rail signal swing. The TS97x
boasts characteristics that make them particularly
well suited for portable and battery-suppliedequip-
ment. Very low noise and low distortion charac-
teristics make them ideal for audio
pre-amplification.

The TS971 is housed in the space-saving 5 pins
SOT23 package which simplifies the board design
because of the ability to be placed everywhere
(outside dimensions are 2.8mm x 2.9mm)

Notes: 1. All voltages values, except differential voltage are with respect to network ground terminal.
2. Differential voltages are non-inverting input terminal with respect to the inverting input terminal.
3. The magniture of input and outputvoltages must never exceed VCC +0.3V.
4. Short-circuits can cause excessive heating and destructive dissipation.
