Description
The TS922 is a rail-to-rail dual BiCMOS
operational amplifier optimized and fully specified
for 3V and 5V operation.
The device’s high output current allows low-load
impedances to be driven.
Very low noise, low distortion, low offset and a
high output current capability make 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.
