Working Principles

The MAX19586ETN+D utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. The analog input voltage is sampled and held, and then the internal SAR circuitry performs a binary search to determine the digital representation of the input voltage. The resulting digital code is then output through the serial data interface.
