Vishay – DG2592: Audio Jack Detector with Send/End Detect

Analog Signal Chain

The DG2592 is an audio jack detector and pop noise control switch IC that features integrated circuits for detecting the presence of a stereo headset with a microphone and send/end control button.

The device features a wide operating range of 1.6V to 5.5V, low quiescent current of 10μA max. at 1.8V, and a 1.2Ω max. MIC bias switch for quick discharge and clamping. The detector offers ESD tolerance >8kV (human body model). When there is no ear phone detected, the DG2592 connects the microphone bias line to ground through the MIC pin.
