Working Principles

The MAX125CEAX+T 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 signal. The ADC samples the analog input at a high rate and compares it to a reference voltage. By iteratively adjusting the comparison, the ADC converges on the digital value that best represents the input signal.
