NCX8193
Audio jack detection and configuration with false detection
prevention
Rev. 2 — 21 November 2014
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.
2. Features and benefits
Fail-safe headset and headphone detection
Low-power standby mode
Click free switching
Low THD and noise microphone pass through channel
Send/End button detection
Low ON resistance: 0.9 (typical) at a supply voltage of 2.8 V
ESD protection:
HBM JEDEC JDS-001 Class 3B exceeds 8 kV
Operating ambient temperature 40C to +85C
3. Applications
Headphones with integrated microphone and remote control buttons
