www.vishay.com DG2592 Vishay Siliconix Audio Jack Detector with Send / End Detect DESCRIPTION The DG2592 is an audio jack detector and pop noise control switch IC. It integrates the circuits necessary to detect the presence of a stereo headset with a microphone and send / end control button. When there is no ear phone detected, the DG2592 connects the microphone bias line to ground through the MIC pin. The DG2592 also gives a logic high signal to the baseband controller through the DET pin. The DG2592 senses the DC levels at both L_Detect and GND_Detect. When an ear phone is plugged in, the voltage at both pins will go low. The DG2592 will indicate the presence of the ear phone by pulling DET low and the MIC switch will turn off. The DG2592 is available in small miniQFN10 of 1.4 mm x 1.
