Working Principles

The AD574AKN utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It employs an internal reference voltage and a comparator to compare the input voltage with a series of binary-weighted voltages. The SAR iteratively adjusts the binary code until it converges to the closest digital representation of the input voltage.
