6.4 Device Functional Modes

The OPA598 has two modes of operation. The first mode is normal operation where the amplifier is enabled, either by supplying a voltage to the enable-disable (E/D) pin that is between 2.5V and 5V greater than the E/D Com pin or by leaving E/D pin floating. The second mode of operation is a low-power, disabled state where the E/D pin is driven between 0V and 0.65V greater than the E/D Com pin. In this state, the amplifier output is disabled and enters a high output impedance state.
