Abstract
This document discusses, among other things, circuits and methods for providing an indication of an impedance between a detecting pin and a first signal pin of an audio socket using first and second comparators to, among other things, determine if moisture is present in the audio socket. If moisture is present in the audio socket, communication between an audio processing unit and the audio socket can be disabled.
