Introduction

AI Translation

The TS20 is 20- Channel capacitive sensor with auto sensitivity calibration. And the supply voltage range is from 2.5 to 5.0V. The TS20 offers LED drivers with 16 steps dimming controller. The CS1~CS20 ports can be used for PWM output for LED dimming control. The TS20 offers a tact switch input. The CS1~CS20 ports can be used for a tact switch input. The result of touch sensing can be checked by the I²C serial interface.
