General Description

The XPT2046 is a 4-wire resistive touch screen controller that incorporates a 12-bit 125 kHz sampling SAR type A/D converter. The XPT2046 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 XPT2046 can detect the pressed screen location by performing two A/D conversions. In addition to location, the XPT2046 also measures touch screen pressure.On-chip VREF can be utilized for analog auxiliary input, temperature measurement and battery monitoring withthe ability to measure voltage from 0V to 5V. The XPT2046 also has an on-chip temperature sensor The XPT2046 is available in 16pin QFN thin package(0.75mm in height) and has the operating temperature range of -40°C to +85°C
