Working Principles

The MAX186CEWP 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 closely matches the input voltage. This process continues until the desired resolution is achieved.
