A capacitive touchscreen detects changes in capacitance to determine the location of one or more fingers on the surface of the touchscreen. A typical touchscreen system consists of a capacitive touchscreen sensor, an FPC bonded to the sensor, and the touchscreen controller mounted on the FPC or PCB. The touchscreen controller then connects to a host processor. Users can interact with the displayed user interface through finger movements and gestures on the surface of the touchscreen.

The IAAT818X is a capacitive touchscreen controller with the sensing and processing technology to resolve the locations and report the positions of up to ten fingers on the touchscreen. The touchscreen controller converts an array of sensor capacitances into an array of digital values, which are processed by touch-detection and position-resolution algorithms in the controller. These algorithms determine the location and signal magnitude of each finger on the touchscreen. This unparalleled versatility eases design challenges and accelerates go-to-market strategies, allowing seamless integration with existing systems.
