Working Principles

The AD5541CR is based on the successive approximation register (SAR) architecture. It utilizes a capacitive digital-to-analog converter (DAC) to compare the input analog voltage with a binary-weighted ladder network. The SAR algorithm iteratively determines the most significant bits (MSBs) of the digital output by comparing the DAC's output with the input voltage. This process continues until all 16 bits are determined, resulting in a precise digital representation of the analog input.
