Description
The TS924 is a rail-to-rail quad BiCMOS
operational amplifier optimized and fully specified
for 3 V and 5 V 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.
