Working Principles

The ADC101S021CIMF/NOPB utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It employs a binary search algorithm to determine the digital representation of the input voltage.

The conversion process starts by setting the most significant bit (MSB) of the output register to the midpoint of the ADC's input voltage range. The ADC then compares this value with the input voltage and adjusts the MSB based on the comparison result. This iterative process continues until all bits are determined, resulting in a digital representation of the input voltage.
