Working Principles

The AD7651ASTZRL utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It employs a sample-and-hold circuit to capture the input voltage, followed by a comparator that compares the sampled voltage with a reference voltage. The SAR then iteratively determines the most significant bits (MSBs) of the digital output until the entire conversion is completed.
