Working Principles

The ADC081S021CIMF/NOPB operates by sampling the analog input voltage and converting it into a digital value using an internal successive approximation register (SAR) architecture. The analog signal is compared to a reference voltage, and the converter determines the digital code that best represents the input voltage. This digital code is then transmitted through the SPI interface for further processing or analysis.
