DESCRIPTION

The TS922 is a RAILTO RAILdual BiCMOS
operational amplifier optimized and fully specified
for 3V and 5V operation.
High outputcurrent allows lowload impedancesto
be driven.
The TS922exhibitsa verylow noise,lowdistortion,
lowoffsetandhighoutputcurrentcapabilitymaking
this devicean excellent choicefor high quality,low
voltage or battery operatedaudio systems.
The device is stable for capacitive loads up to
500pF.

Notes : 1. All voltage values,except differentialvoltage are withrespect to networkground terminal.

2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.

3. The magnitude of input and output voltages must never exceed V

+0.3V.

4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all amplifiers.
