7.4 Device Functional Modes

The OPAx211 is operational when the power-supply voltage is greater than 4.5 V (±2.25 V). The maximum

power supply voltage for the OPAx211 series is 36 V (±18 V).

7.4.1 Shutdown

The shutdown (enable) function of the OPA211 is referenced to the positive supply voltage of the operational

amplifier. A valid high disables the operational amplifier. A valid high is defined as (V+) – 0.35 V of the positive

supply applied to the shutdown pin. A valid low is defined as (V+) – 3 V below the positive supply pin. For

example, with VCC at ±15 V, the device is enabled at or below 12 V. The device is disabled at or above 14.65 V.

If dual or split power supplies are used, make sure the valid high or valid low input signals are properly referred

to the positive supply voltage. This pin must be connected to a valid high or low voltage or driven, and not left

open-circuit. The enable and disable times are provided in the Typical Characteristics section (see Figure 39

through Figure 41). When disabled, the output assumes a high-impedance state.
