AK4186  
Low Power Touch Screen Controller with I2C Interface  
GENERAL DESCRIPTION  
The AK4186 is a 4-wire/ 5-wire resistive touch screen controller that incorporates 12bit SAR A/D  
converter. The AK4186 can detect the pressed screen location with two A/D conversions and it can also  
measure touch pressure. The AK4186 has both an automatic continuous measurement and a  
measurement data calculation function. The functions that normally require external processing, such  
as calculating the average screen input value, are processed by the AK4186. In addition, a new  
sequential mode achieves short coordinate measurement time while greatly reducing the  
microprocessor overhead. The AK4186 operates off of supply voltage down to 1.6V in order to connect  
a low voltage microprocessor. The AK4186 is the best fit for cellular phone, DSC, DVC, smart phone  
and other portable devices.
