Touch Screen Controller  
AK4181A  
General Description:  
Features:  
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.
