Description

The AK4180 is a 4-wire touch screen controller that incorporates a 12-bit 125kHz sampling SAR A/D converter. The product can detect the pressed screen location by performing two A/D conversions. In addition to location, the AK4180 also measures touchscreen 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 AK4180 also has an on-chip temperature sensor.
