Working Principles

The AD670SD/883B is an analog-to-digital converter that operates based on the successive approximation technique. It converts analog input voltages into corresponding digital values using a 12-bit resolution. The input voltage is compared to a reference voltage, and the converter iteratively approximates the digital value by adjusting the comparison level. This process continues until the digital output accurately represents the input voltage.
