| Voltage Reference |
The ADS7846N is a 12-bit, 4-wire resistive touch screen controller from Texas Instruments, designed for battery-operated portable devices. It communicates via an SPI interface and supports both external and internal voltage references, including an on-chip 2.5V reference. The device operates over a supply voltage range of 2.2V to 5.25V with a typical supply current of 500 µA.
This controller integrates direct battery measurement (0V to 6V), on-chip temperature measurement, and touch-pressure measurement capabilities. It is a next-generation version of the industry-standard ADS7843 and is 100% pin-compatible, allowing for easy upgrades with only software changes.
The ADS7846N is specified for operation from -40°C to +85°C and is available in a surface-mount 16-TSSOP package. Its low power consumption and high-speed clock rate (up to 125 kHz) make it suitable for personal digital assistants, portable instruments, point-of-sale terminals, pagers, touch screen monitors, and cellular phones.
