Working Principles

The MAX197BCAI 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 input analog signal is compared to a reference voltage, and the converter determines the digital value by iteratively adjusting the comparison until the desired accuracy is achieved.
