GH612/613 - High Performance, Low Power Capacitive Touch Chip


GH612/613 is a high-performance capacitive touch chip with low power consumption, can be used in ultra-low power capacitive touch key detection for IoT and wearable devices. Integrated with a high-performance, low-power MCU and a self-inductance front-end analogue circuit, GH612/613 detects the touch event or proximity sensing to implement corresponding human-computer interaction based on the changes of capacitance. GH612/613 adopts the sensing algorithm that is proprietarily researched and developed by Goodix. Its super-high signal-to-noise ratio enables it to identify proximity sensing accurately, along with gestures like slide, tap/click and long-press.
