Working Principles

The AD669AR is an analog-to-digital converter that operates by sampling the input analog voltage and converting it into a digital representation. It utilizes a successive approximation algorithm to achieve high-resolution conversion. The input voltage is compared to a reference voltage, and the converter iteratively adjusts the digital output until it matches the input voltage within the specified resolution.
