Working Principles

The MAX19706ETM+ operates based on the successive approximation register (SAR) architecture. It converts analog input voltages into 16-bit digital data using a combination of sample-and-hold, comparator, and digital control circuitry. The internal SAR algorithm iteratively approximates the input voltage by comparing it with a reference voltage and adjusting the output code accordingly. This process continues until the desired resolution is achieved.
