DESCRIPTION

The TS921is a RAILTO RAILsingle BiCMOS
operational amplifier optimized and fully specified
for 3V and 5V operation.
High outputcurrent allowslowload impedancesto
be driven.
The TS921exhibitsa verylownoise,lowdistortion,
low offsetand high ouput currentcapabilitymaking
this devicean excellent choicefor high quality,low
voltage or battery operated audio systems.
The device is stable for capacitive loads up to
500pF.
