Azoteq IQS263B ProSense IC is a 3-channel capacitive proximity and touch controller with class sensitivity, Signal to Noise Ratio (SNR) and power consumption. The device has 4 pins for connection of sense electrodes, which consist of 3 self electrodes, or 3 receivers and 1 transmitter. IQS263B IC's automatically track varying environmental changes via filters, detects noise and is equipped with an Automatic Tuning Implementation (ATI) for optimal sensitivity. These ProSense IC's work on a chip movement detection algorithm.
