7.4 Device Functional Modes

The OPAx354-Q1 family of devices is powered on when the supply is connected. The devices operates as a single-supply operational amplifier or dual-supply amplifier 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).
