DESCRIPTION
TS971ID-TS971IDT
The TS97x family operational amplifiers is able to
operate with voltages as low as
±1.35V
and fea-
turing 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 char-
acteristics make them ideal for audio pre-amplifi-
cation.
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)

All voltage values, except differential voltage are with respect to network ground terminal.
Differential voltages are the non-inverting input terminal with respect to the inverting input t erminal.
The magnitude of input and output voltages must never exceed V
CC
+0.3V.
Short-circuits can cause excessive heating and destructive dissipation.
