Working Principles

The AD42377 is an analog-to-digital converter that converts continuous analog signals into discrete digital values. It utilizes a successive approximation algorithm to achieve high-resolution conversion. The input analog voltage is compared against an internal reference voltage, and the converter determines the digital representation based on this comparison. The converted digital value is then output through the serial interface.
