Description

The TS97x family operational amplifiers is able to
operate with voltages as low as ±1.35V and fea­turing output rail-to-rail signal swing. The TS97x
boasts characteristics that make them 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 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).

Applications

■ Portable equipment (CD players, PDA)

■ Portable communications (cell phones,

pagers)

■ Instrumentation & sensoring

■ Professional audio circuits

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.

5) Human body model, 100pF discharged through a 1.5kΩ resistor into pin of device.
