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.
