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.
