DESCRIPTION
The TS921 is a RAIL TO RAIL single BiCMOS
operational amplifier optimized and fully specified
for 3V and 5V operation.
High output current allows low load impedances to
be driven.
The TS921 exhibits a very low noise, low distortion,
low offset and high ouput 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.

All voltage values, except differential voltage are with respect to network ground terminal.
Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
The magnitude of input and output voltages must never exceed VCC+ +0.3V.
Short-circuits can cause excessive heating.
