Working Principles

The MAX19515ETM+ 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 by successively approximating the input voltage. This process continues until the desired resolution is achieved.
