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-supplied equip-
ment. Very low noise and low distortion charac-
t e r is t ic s ma k e t h em id e a l f o r a ud io
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 equipments (CD players, PDA)
Portable communications (cell phones, pagers)
Instrumentation & sensoring
Professional audio circuits

Notes:

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