Working Principles

The ADC124S101CIMMX operates based on the successive approximation register (SAR) architecture. It samples the analog input voltage and converts it into a digital value using a binary search algorithm. The internal circuitry compares the input voltage against a reference voltage and iteratively determines the most significant bits (MSBs) first, followed by the least significant bits (LSBs). This process continues until the desired resolution is achieved.
