Capacitive to Digital & Touch Screen Controllers

Analog Devices’ portfolio of capacitance-to-digital converters (CDCs) and touch screen controllers provide solutions for your automotive, industrial, medical, and other system needs, with applications including humidity, position, and proximity sensing.
Our CDC products provide a new standard in single-chip solutions, with members of this portfolio providing high resolution, high linearity, and high accuracy, as well as fast response times and high input sensitivity. Our touch screen controllers feature a synchronous serial interface ,low on-resistance switches for driving touch screens, and throughput rates greater than 125 kSPS.
