Overview
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 for 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 such as headphone wearing/non-wearing, swipe, single/double tap and long press.
