Overview

[AK4186] 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...
