The ADS7846N/2K5 from Texas Instruments is a 12-bit touch screen controller designed for 4-wire resistive touch screen applications. It offers a versatile operating voltage range of 2.2V to 5.25V and can function in temperatures from -40°C to 85°C.
This controller utilizes an SPI interface for communication and includes features such as an internal 2.5V reference, direct battery measurement capability (0V to 6V), and on-chip temperature measurement. It is designed for low-power consumption, making it suitable for battery-operated devices. The device supports both external and internal voltage references and has a typical current consumption of 500 µA.
The ADS7846N/2K5 is available in a 16-TSSOP package, a surface-mount type, with dimensions of 5 mm x 6.4 mm. It is a next-generation version of the ADS7843, offering pin compatibility for easy upgrades. Applications include personal digital assistants, portable instruments, point-of-sales terminals, pagers, touch screen monitors, and cellular phones.
