Touch Screen Controller

The AK4181A is a 4-wire Touch Screen controller that incorporates a 12-bit 125kHz sampling SAR A/D converter The AK4181A CAN detect the pressed screen location by performing two A/D conversions. In addition to location, the AK4181A also measures Touch Screen pressure. On-chip VREF CAN be utilized for two Analog auxiliary inputs and battery monitoring, with the ability to measure voltages from 0V to 5V. The AK4181A also has an on-chip Temperature Sensor By AKM Semiconductor, Inc.
