AK4185
Ultra Small Package SPI* Touch Screen Controller
The AK4185 is a 4-wire/ 5-wire resistive touch screen controller housed in an ultra small package. The AK4185 has two high performance A/D converters enabling to detect pressed location and to measure its pressure. The AK4185 operates at a single supply voltage down to 1.6V, allowing to interface a low voltage microprocessor, and  is ideal for portable/mobile applications requiring high performance touch screen sensing with low power and small footprint such as mobile phones, DSCs/DVCs, and PMPs.
