Working Principles

The AD5544ARS is based on the successive approximation register (SAR) architecture. It utilizes a capacitive digital-to-analog converter (DAC) to compare the input analog signal with a binary search algorithm. The SAR ADC iteratively adjusts the DAC's output until it matches the input voltage, resulting in a digital representation of the analog signal.
