Abstract
This document discusses, among other things, an audio jack detection switch configured to be coupled to first and second GND/MIC terminals of an audio jack, wherein the audio jack detection switch includes a detection circuit configured to measure an impedance on the first and second GND/MIC terminals and identify each GND/MIC terminal as either a GND pole or a MIC pole using the measured impedance, and wherein the audio jack detection switch includes a switch configured to automatically couple an identified MIC pole to a MIC connection and to automatically couple an identified GND pole to a GND connection using information from the detection circuit.
