Working Principles

The XR3085XEDTR-F is an analog-to-digital converter (ADC) that converts continuous analog signals into discrete digital values. It utilizes a successive approximation algorithm to achieve high-resolution conversion. The analog input voltage is compared to a reference voltage, and the ADC iteratively approximates the input voltage by adjusting its internal digital-to-analog converter (DAC) until the difference between the input and the DAC output is minimized. This process continues until the desired resolution is achieved.
