The AK4184 is a 12-bit A/D converter witch operates 125kHz (max) sampling rate with a 4-wire resistive touch screen controller (TSC), including low-on resistance switches, touch pressure measurement capability, a maximum 6 x 5 keypad scanner, eight GPIO ports, and a PWM generator for LED contrast control.
The AK4184 operates down to a 2.5V supply voltage, and it tolerates digital I/O interface voltage from 1.6V to AVDD in order to connect to low voltage controllers.
The AK4184 supports SPI interface for communication to a host controller.
