Product Specification

The GT308L is one of the new GreenTouch3TM capacitive touch sensor series. Especially the GT308L can do capacitance sensing with 8 channels under above GreenTouch3TM engine operation.

Thanks to this epochal GreenTouch3TM engine, the applications will be more robust and problem free against EMC, EMI, H/W variations, voltage disturbance, temperature drift, humidity drift and so on.

Especially, it doesn't make any issue against CS and EFT noise environments occurred in any touch applications.
The GT308L offers 8 LED drivers with 16 steps dimming controller. The OUT1~8 pins can be used for PWM output for LED dimming control. It’s very economical solution when the LED feedbacks are required because there is no additional material cost for LED control.
For the touch output result, the I2C or 1:1 direct output interface can be used. I2C interface might be useful when the MCU IO or connector resource is not enough in the application.
The GT308L can be applied under wide supply voltage range from 2.5V to 5.5V. And it has CTRL pin to select sensitivity options and I2C-bus slave address by making the pin connection to VDD, GND and OPEN.
