Working Principles

The AD558KN is an 8-bit successive approximation analog-to-digital converter. It operates by comparing the input analog voltage with a reference voltage and successively narrowing down the digital representation until a match is found. The conversion process is controlled by an internal clock signal, and the result is available at the digital output pin.
