Working Principles

The CP8398AT is an analog-to-digital converter that converts continuous analog signals into discrete digital values. It utilizes a successive approximation algorithm to determine the digital representation of the input voltage. The ADC samples the analog input voltage at a high speed and compares it to a reference voltage. By iteratively adjusting the digital code, the ADC converges to the closest digital value that represents the input voltage accurately.
