Working Principles

The AD569AD utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It employs an internal reference voltage generator and a comparator to compare the input signal with a series of binary-weighted voltages. The converter iteratively adjusts the binary code until it converges to the closest digital representation of the analog input.
