ADS7846E/2K5 Description

Short technical summary and product information.

The ADS7846E/2K5 is a 12-bit touch screen controller from Texas Instruments designed for 4-wire resistive touch screens. It communicates via an SPI interface and operates from a supply voltage of 2.2V to 5.25V, with a typical supply current of 500 µA. The device includes an internal 2.5V reference that supports direct battery measurement (0V to 6V), on-chip temperature measurement, and touch-pressure measurement. Auto power-down functionality helps conserve power in battery-operated systems.

 

The controller is available in a 16-SSOP surface-mount package and is specified over the -40°C to +85°C temperature range. It is 100% pin-compatible with the ADS7843, allowing easy upgrades with only software changes. Typical applications include personal digital assistants (PDAs), portable instruments, point-of-sale terminals, pagers, touch screen monitors, and cellular phones.
