Product Introduction
Capacitive Touch Chip- GTX312L is a GreenTouch 3LPTMOne of the capacitive touch products in the sensor series. EspeciallyGTX312LCan perform capacitive sensing with more than 12 channels running on the GreenTouch 3LPTMEngine running. Due to GreenTouch 3LPTMThe low-power engine allows various battery-powered applications to increase product usage time. Also, based on the existing GreenTouch3TM engine technology, reliability can be guaranteed against various noises and environmental changes. Internal control registers can be accessed via the I2C read/write interface.
GTX312L can operate over a wide supply voltage range from 1.8V to 5.5V. The CTRL pin of GTX312L provides a switchable chip ID for I2C bus operation of two chips in parallel on the same bus.
