The AK4182 is a 4-wire resistive touch screen controller
that incorporates a 12-bit 125 kHz sampling SAR type
A/D converter.
The AK4182 operates down to 2.2V supply voltage and
supports digital I/O interface voltage from 1.5V to VCC in
order to connect low voltage uP.
The AK4182 can detect the pressed screen location by
performing two A/D conversions. In addition to location,
the AK4182 also measures touch screen pressure.
On-chip VREF can be utilized for analog auxiliary input,
temperature measurement and battery monitoring with
the ability to measure voltage from 0V to 5V.
The AK4182 also has an on-chip temperature sensor.
The AK4182 is available in 16pin QFN thin package
(0.75mm in height) and has the operating temperature
range of -40°C to +85°C
