Working Principles

The MAX385CPE 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-speed and accurate conversion. The input analog voltage is compared to a reference voltage, and the converter determines the digital representation by iteratively approximating the input voltage. The converted digital data is then available for further processing or storage.
