Working Principles

The ADS7816EB/2K5 operates based on the successive approximation register (SAR) architecture. It uses a capacitor-based digital-to-analog converter (DAC) and a comparator to perform the analog-to-digital conversion. The input analog signal is sampled, and the ADC iteratively adjusts the DAC's output to match the input voltage. The conversion process continues until the DAC output matches the input voltage within the desired resolution.
