Product data sheet
1. General description
The NCX8193 is an advanced audio jack accessory detector and controller.
It supports 3-pole and 4-pole connectors and detects the insertion of plugs into jacks
using a fault detection technique. An internal microphone bias line switch allows a codec
or application processor to control the audio jack configuration. The device supports a
broad variety of after-market headphones.
