Working Principles

The MAX1401EAI+T is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The input analog voltage is compared against a reference voltage, and the converter determines the digital representation based on the comparison results. The converted digital data is then transmitted through the serial interface for further processing.
