Working Principles

The ADC081C021CIMM/NOPB operates by sampling the analog input voltage and converting it into a digital value. It uses an internal successive approximation register (SAR) architecture to perform the conversion. The analog input voltage is compared to a reference voltage, and the SAR iteratively approximates the digital value by adjusting the comparison. Once the conversion is complete, the digital value is available for further processing.
