Q: Customer wants a circuit that will enable/disable the DRV602 based upon whether or not a cable is plugged into the output connector (RCA/phono jack).
A: Recommended schematic attached.
Additional notes: the Mute_L and Mute_R signals should be used to Mute the input signals that are fed to the DRV602. Also, in actual implementation, caps to GND may need to be placed at the inputs to the OR gate to perform low pass filtering.
