The XPT2046 is a 4-wire resistive touch screen controller incorporating a 12-bit, 125 kHz sampling SAR type A/D converter. It is designed for low voltage operation, with a supply voltage range from 2.2V to 6V. The digital I/O interface supports voltages from 1.5V to VCC, allowing connection to low voltage microprocessors.
This controller can detect the pressed screen location through two A/D conversions and also measures touch screen pressure. An on-chip voltage reference (2.5V) is included, and it can be utilized for analog auxiliary input, temperature measurement, and battery monitoring, capable of measuring voltages from 0V to 5V. The device exhibits low power consumption, drawing only 260 uA.
The XPT2046 is available in a 16-pin QFN package. Its applications include POS terminals, portable LCD-based instruments, pager systems, touch screen monitors, and cellular phones.
