Touch Screen Controller

AK4182A

General Description:

Features:

The AK4182A is a 4-wire resistive touch screen

controller that incorporates a 12-bit 125 kHz sampling

SAR type A/D converter.

The AK4182A 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 AK4182A can detect the pressed screen location by

performing two A/D conversions. In addition to location,

the AK4182A 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 AK4182A also has an on-chip temperature sensor.

The AK4182A is available in 16pin QFN thin package

(0.75mm in height) and has the operating temperature

range of -40°C to +85°C
