GH610/611 - 2-in-1 Capacitive In-Ear Detection and Touch Control Chip


GH610/611 offers a capacitive 2-in-1 solution of in-ear detection (IED) and touch control, which can be applied to the in-ear/touch key detection in smart headphones. Integrated with a high-performance, ultra-low power consumption MCU and self-inductance front-end circuit, GH610/611 implements in-ear detection and touch operations according to the changes of capacitance to control the corresponding human interface based on the sensing algorithm independently developed by Goodix. GH610/611 has a super-high signal-to-noise ratio and can precisely identify the operation status like headphone wearing/non-wearing, swipe, single/double tap and long press.


  • Precise, reliable, and low-power capacitive multi-channel in-ear detection and touch key detection

  • More convenient and easier interaction between users and devices: supports operations like upward and downward swipe, single/double tap and long press

  • Automatic thermal drift compensation

  • Embedded MCU with low power consumption

  • Channels:

    1. GH610 supports 1-channel touch key with 2-channel in-ear detection
    2. GH611 supports 3-channel touch keys with 2-channel in-ear detection
  • Supports 1.7V ~ 5.5V wide voltage power supply

  • On-chip memory: 3.5KB SRAM

  • Clock: an internally calibrated capacitance-resistance oscillator (no external crystal oscillator required)

  • Package: WLCSP 19 Pin 2.09 mm * 1.94 mm * 0.513 mm
