Working Principles

The AD522BD is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation algorithm to determine the digital representation of the input voltage. The input voltage is compared to a reference voltage, and the converter iteratively adjusts the digital output until it matches the input voltage within the desired resolution.
