Working Principles

The MAX136CQH+D is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation algorithm to achieve high-resolution conversion. The input analog signal is compared to a reference voltage, and the converter determines the digital representation based on this comparison. The digital output is then transmitted through the serial interface for further processing.
