SBOS659B January 2022 – August 2022 OPA593
The OPA593 has two modes of operation. The first mode is normal operation where the amplifier is enabled, either by supply a voltage to the enable-disable (E/D) pin that is between 2.5 V and 5 V greater than the E/D Com pin. The second mode of operation is a lower-power, disabled state where the E/D pin is driven between 0 V and 0.65 V greater than the E/D Com pin. In this state, the amplifier output is disabled and enters a high output impedance state.
