Working Principles

The MAX186DEWP+T is an analog to digital converter (ADC) that converts continuous analog signals into discrete digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input voltage is compared to a reference voltage, and the SAR iteratively approximates the input voltage by adjusting the digital code. Once the conversion is complete, the digital output is available for further processing or storage.
