DESCRIPTION
The TS924 is a RAIL TO RAIL quad BiCMOS
operational amplifier optimized and fully specified
for 3V and 5V operation.
High output current allows low load impedances to
be driven.
The TS924 exhibits a very low noise, low distortion,
low offset and high output current capability making
this device an excellent choice for high quality, low
voltage or battery operated audio systems.
The device is stable for capacitive loads up to
500pF.
APPLICATIONS
. headphoneamplifier
. piezoelectric speaker driver
. sound cards
. MPEG boards, multimedia systems, ...
. line driver, buffer
. cordless telephones and portable communica-
tion equipment
. instrumentation with low noise as key factor

Notes :
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. Destructive dissipation can result from simultaneous short-circuit on all amplifiers.
