7.4 Device Functional Modes

The OPAx180, OPA2180 , and OPA4180 devices are powered on when the supply is connected. These devices can operate as a single-supply operational amplifier or dual-supply amplifier depending on the application. In single-supply operation with V– at ground (0V), V+ can be any value between 4V and 36V. In dual-supply operation, the supply voltage difference between V– and V+ is from 4V to 36V. Typical examples of dual-supply configuration are ±5V, ±10V, ±15V, and ±18V. However, the supplies must not be symmetrical. Less common examples are V– at –3V and V+ at 9V, or V– at –16V and V+ at 5V. Any combination where the difference between V– and V+ is at least 4V and no greater than 36V is within the normal operating capabilities of these devices.
