Working Principles

The AD574ALD utilizes successive approximation register (SAR) architecture to convert analog signals into digital data. It employs a capacitor-based digital-to-analog converter (DAC) and a comparator to perform the conversion process. The input analog signal is compared with the DAC output, and the comparator's decision is used to determine the digital representation of the input signal.
