8.4 Device Functional Modes

The OPAx354 family of devices is powered on when the supply is connected. The devices can operate as single-supply operational amplifiers or dual-supply amplifiers depending on the application. The devices are used with asymmetrical supplies as long as the differential voltage (V– to V+) is at least 1.8 V and no greater than 5.5 V (example: V– set to –3.5 V and V+ set to 1.5 V).
