Working Principles

The MAX1243ACPA 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 against a reference voltage, and the converter iteratively adjusts its internal digital code until it converges to the closest digital value representing the input voltage.
