摘要： Apparatus and methods for detecting audio jack connection anomalies such as moisture or a partial insertion of an audio jack plug with an audio jack receptacle are provided. In an example, a method for detecting an audio jack insertion anomaly can include ramping on a first detection current source of a detection circuit coupled to a detection terminal of a first audio jack connector, receiving a reference information at a comparator of the detection circuit, receiving a voltage of the detection terminal at the comparator, providing comparison information at an output of the comparator, the comparison information indicative of a comparison of the voltage of the detection terminal and the reverence information, and wherein a first state of the comparison information indicates the audio jack insertion anomaly is due to moisture at the first audio jack connector.

摘要： 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.
