GH610 offers a capacitive 2-in-1 solution of in-ear detection (IED) and touch control for in-ear / touch key detection of smart earphones. Integrated with a high-performance, low-power MCU and self-capacitance front-end circuit, GH610 can perform IED and touch operations based on capacitance changes, thus realizing control over the corresponding human interface. Supported by our self-developed sensing algorithm, GH610 ensures a super-high signal-to-noise ratio and precisely identifies the earphone status (in/out ear) as well as operations like swipe, single / double tap, and long press.
