描述 Description

The IQS269A ProxFusion® IC is an 8-channel self/mutual-capacitive proximity and touch controller with best in class sensitivity, signal to noise ratio and power consumption. In addition, the device offers mixed sensing abilities such as Hall-effect and inductive sensing.  Other features include automatic tuning and differential offset compensation for sense electrodes.
