Working Principles

The MAX1285BESA 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 with 12-bit accuracy. The input voltage is compared to an internal 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 or storage.
