Working Principles

The MAX186BEWP is an analog-to-digital converter that converts analog signals into digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input voltage is compared to the internal reference voltage, and the converter iteratively approximates the digital representation of the input signal. The converted digital data is then outputted serially.
