Working Principles

The MAX128AEAI+ utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It employs a comparator, a digital-to-analog converter (DAC), and a control logic unit to iteratively approximate the input voltage and generate the corresponding digital output.

The analog input voltage is compared with the DAC-generated voltage, and the result is fed back to the control logic unit. This process continues until the digital output accurately represents the input voltage.
