ADS7817UC

Analog To Digital Converters (ADC) Overview

The ADS7817UC is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Burr-Brown. It features a high-impedance fully differential analog input and operates on a single 5V supply, consuming only 2.3 mW of power. The device supports sampling rates up to 200 kS/s with an external reference voltage range of 100 mV to 2.5 V. It communicates via a 3-wire serial interface compatible with SPI. Packaged in an 8-pin MSOP, it is designed for battery-operated systems requiring low power consumption and small form factors.
