Working Principles

The MAX122BCNG is an analog-to-digital converter that converts continuous analog signals into discrete digital data. 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 rate and compares it to a reference voltage. By iteratively adjusting the comparison, the ADC converges on the digital code that best represents the input voltage.
