The ADS7846 from Texas Instruments is a 4-wire touch screen controller designed as a pin-compatible upgrade to the ADS7843. It supports a wide operating voltage range of 2.2V to 5.25V and includes an internal 2.5V reference.
Key features include direct battery measurement from 0V to 6V, on-chip temperature measurement, and touch-pressure measurement capabilities. The device utilizes a QSPI/SPI 3-wire interface and supports auto power-down for low-power consumption, typically less than 0.75mW at 2.7V with the reference off. It can operate at clock rates up to 125kHz.
The ADS7846 is specified for operation over a temperature range of -40°C to +85°C. It is available in multiple package options including TSSOP-16, SSOP-16, QFN-16, and VFBGA-48, making it suitable for various portable and battery-operated systems.
Applications for the ADS7846 include personal digital assistants (PDAs), portable instruments, point-of-sale terminals, pagers, touch screen monitors, and cellular phones.
