DESCRIPTION
The TS921 is a RAIL TO RAIL single BiCMOS
operational amplifier optimized and fully specified
for 3V and 5V operations.
It exhibits a very low noise, low distortion and high
output current capability making this device an
excellent choice for high quality, low voltage or
battery operated audio systems.
The TS921 remains stable when charging the output with 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.
