NCX8200 - Audio jack configuration switch matrix

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.

Features

  • 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: 40C to +85C.
  • 1.22 mm  1.22 mm  0.5 mm WLCSP9 package 3.

NCX8200 Audio jack configuration switch matrix Rev. 1 — 15 May 2015 Product data sheet 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.
