Overview
[AK4185] AK4185 Low Power Touch Screen Controller with SPI™ Interface GENERAL DESCRIPTION The AK4185 is a 4-wire/ 5-wire resistive touch screen controller that incorporates 12bit SAR A/D converter.
The AK4185 operates down to 1.
6V supply voltage in order to connect a low voltage microprocessor.
The AK4185 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 AK4185.
In addition, a new sequential mode achieves short coordinate measurement time while greatly reducing the microprocessor overhead.
The AK4185 can detect the pressed screen location by performing two A/D conversions and it can also measure touch pressure.
The AK4185 is the best fit for cellular phone, DSC, DVC, smart phone, or other portable devices.
