1. General description
The NCX8200 is an advanced audio jack configuration switch matrix device that supports 3- and 4-pole connectors. It allows reconfiguration of the GND, microphone-bias contact to comply with the American Headset Jack (AHJ) and the Open Mobile Terminal Platform (OMTP) pinout. Furthermore, a GND sense path supports quasi-differential amplifier architectures. The device contains Human Body Model compliant ESD protection diodes rated 8 kV at all pins. The device can be operated from a supply in the range of 1.6 V to 3.6 V. It supports a broad variety of after-market headphones.
2. Features and benefits
AHJ and OMTP headset jack pinout support Low supply current Sense path to GND for quasi differential amplifier configuration Low THD and noise microphone pass through channel Ultra low RDSon of ground and sense switches High power supply ripple rejection ESD protection: HBM JEDEC JDS-001 Class 3B exceeds 8 kV Operating ambient temperature: 40C to +85C 1.22 mm 1.22 mm 0.5 mm WLCSP9 package
