NCX8200UK012 1. General description

The NCX8200 is an advanced audio jack configuration switch matrix device that supports3- and 4-pole connectors. It allows reconfiguration of the GND, microphone-bias contactto comply with the American Headset Jack (AHJ) and the Open Mobile Terminal Platform(OMTP) pinout. Furthermore, a GND sense path supports quasi-differential amplifierarchitectures. The device contains Human Body Model compliant ESD protection diodesrated 8 kV at all pins. The device can be operated from a supply in the range of 1.6 V to3.6 V. It supports a broad variety of after-market headphones.
