DESCRIPTION
The TS922 is a RAIL TO RAIL dual BiCMOS
operational amplifier optimized and fully specified
for 3V and 5V operation.
High output current allows low load impedances to
be driven.
The TS922 exhibits a very low noise, low distor-
tion, low offset and high output current capability
making this device an excellent choice for high
quality, low voltage or battery operated audio sys-
tems.
The device is stable for capacitive loads up to
500pF.
APPLICATIONS

MPEG boards, multimedia systems, ...
s
line driver, buffer
s
cordless telephones and portable communica-
tion equipment
s

1.
All voltages values, except differential voltage are with respect to network ground terminal.
2.
Differential voltagesare the non-inverting input terminal with respect to the inverting input terminal.
3.
The magnitude of input and output voltages must never exceed V

4.
Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all amplifiers
