The Microchip's capacitive touch controller is with 12 configurable Microchip QTouchADC buttons, sliders and wheels. The QTouchADC sensing algorithm self capacitance enables the user to achieve longer-range proximity sensing. This capability makes the device ideal for any typical of proximity-sensing application, including wake-up, thermostat, TV controls, wireless mouse, etc. This reduces the total power consumption of your device and results in a more intuitive and differentiated user interface. The button sensors can be constructed in a variety of shapes and sizes. The device includes all the necessary signal processing functions required to provide stable sensing under a wide variety of changing conditions and frequencies conducted immunity certified to EN61000-4-6 Level 2B.
