The Texas Instruments TSC2046EIRGVT is a versatile 12-bit touch screen controller designed for 4-wire resistive touch screens. It communicates via an SPI interface and supports a wide operating voltage range from 2.2V to 5.25V. This device includes an internal 2.5V reference, which can be utilized for auxiliary inputs, battery monitoring (0V to 6V), and on-chip temperature measurements.
With a low operating current of 780 µA and a sample rate up to 125kHz, the TSC2046EIRGVT is suitable for battery-operated portable equipment. It operates across a temperature range of -40°C to 85°C. The controller exceeds IEC 61000-4-2 ESD requirements with ±15V contact discharge protection.
Available in a compact 16-VQFN exposed pad package, the TSC2046EIRGVT is designed for surface mount applications. Its pinout is compatible with the ADS7846, facilitating easy upgrades in existing designs. Applications include personal digital assistants, portable instruments, point-of-sale terminals, pagers, touch screen monitors, and cellular phones.
