The TS922 is a RAIL TO RAIL dual BiCMOS operational amplifier optimized and fully specified for 3V and 5V operation.
High output current allows low load impedances to be driven.
The TS922exhibitsa very low noise, low distortion, low offsetand high output current capabilitymaking 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.

Notes : 1. All voltage values, except differential voltage are with respect to network ground 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 VCC+ +0.3V. 4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all amplifiers.
