General Description:

Features:

The AK4180 is a 4-wire touch screen controller that incorporates

a 12-bit 125kHz sampling SAR A/D converter. The AK4180 can

detect the pressed screen location by performing two A/D

conversions. In addition to location, the AK4180 also measures

touchscreen pressure.

Sampling Frequency: 125kHz(max)

Pen Pressure Measurement

On-Chip Thermo Sensor

Two Auxiliary Analog Inputs

Direct Battery Measurement

4-wire I/F

On-chip VREF can be utilized for two analog auxiliary inputs

and battery monitoring, with the ability to measure voltages from

0V to 5V.
