Description
The TS924 and TS924A devices are rail-to-rail
quad BiCMOS operational amplifiers optimized
and fully specified for 3 V and 5 V operation.
High output current allows low load impedances
to be driven.
The TS924 and TS924A devices exhibit a very
low noise, low distortion, low offset, and high
output current capability, making these devices an
excellent choice for high-quality, low-voltage, and
battery-operated audio systems.
The devices are stable for capacitive loads up to
500 pF.
