ADS7846E Description

Short technical summary and product information.

The ADS7846E is a 12-bit, 4-wire resistive touch screen controller from Texas Instruments. It is a next-generation version of the industry-standard ADS7843 and is 100% pin-compatible, allowing for easy upgrades. The device operates from a supply voltage of 2.2V to 5.25V and communicates via an SPI 3-wire interface.

 

Key features include an internal 2.5V reference, direct battery measurement from 0V to 6V, on-chip temperature measurement, and touch-pressure measurement. The typical supply current is 500 µA, and power consumption is less than 0.75 mW typical at 2.7V with the reference off. The maximum clock rate is 125 kHz.

 

The ADS7846E is designed for portable and battery-powered applications. It is housed in a 16-SSOP (0.154", 3.90mm Width) surface-mount package and operates over a temperature range of -40°C to 85°C.
