The device features a power-down option. The PD pin is used to power down the amplifier. This pin supports both 1.8‑V and 3.3‑V digital logic, and is referenced to ground. A logic 1 turns the device off and places the device into a low-quiescent-current state.

When disabled, the signal path is still present through the internal circuits. Input signals applied to a disabled device still appear at the outputs at some lower level through this path, as is the case for any disabled feedback amplifier.
