GH6210 – High-Precision Smart Capacitive Sensor

Overview

GH6210 is a 3-channel high-precision smart capacitive sensor. It can be widely utilized in high-sensitivity scenarios including touch and proximity sensing. By leveraging the built-in RF filter circuit, it is highly immune to interference. Each sensing channel can be configured individually. In addition, a low-power data processor is integrated to support differentiated data processing requirements.

In SAR proximity sensing, GH6210 supports a variety of antennas of different sizes and capacitance to ground simultaneously. In HMI applications, it excels for internal 16-bit low-power MCU, supporting a rich set of slide and custom gestures.
