Working Principles

The MAX125CEAX+D is an analog-to-digital converter that converts continuous analog signals into discrete digital values. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input voltage is compared against a reference voltage, and the converter determines the digital value by iteratively approximating the input voltage.
