DESCRIPTION

The TS925 is a RAIL TO RAIL quad BiCMOS operational amplifier optimized and fully specified for 3V and 5V operation.

High output current allows lowload impedancesto be driven. An internal low impedance PHANTOM GROUND eliminates the need for an external reference voltage or biasingarrangement.

The TS925exhibitsavery lownoise,lowdistortion and high output current making this device an excellent choice for high quality, low voltage or battery operatedaudio/telecomsystems.

The device is stable for capacitive loads up to 500pF.

When the STANDBY mode is enabled, the total consumption drops to 6µA(V

2. Differential voltages are thenon-inverting inputterminalwith respecttothe invertinginput terminal.

3. The magnitude ofinput and output voltages must never exceed V

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