The Texas Instruments ADS7846EG4 is a 12-bit resolution 4-wire resistive touch screen controller designed for battery-powered portable devices. It communicates via an SPI interface and supports supply voltages from 2.2V to 5.25V. The device integrates an internal 2.5V reference and provides direct battery measurement up to 6V, on-chip temperature measurement, and touch-pressure measurement. With a typical power consumption of 0.75 mW at 2.7V (reference off) and a maximum clock rate of 125 kHz, it is well-suited for power-sensitive applications.
The ADS7846EG4 is pin-compatible with the industry-standard ADS7843, allowing easy upgrades. It is available in a 16-SSOP package (0.154" width, 3.90mm) with surface-mount mounting. The operating temperature range is -40°C to +85°C. Typical applications include personal digital assistants, portable instruments, point-of-sale terminals, pagers, touch screen monitors, and cellular phones.
