General Description:
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.
The AK4181A also has an on-chip temperature sensor.
