Working Principles

The ADC3443IRTQR utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It samples the analog input voltage at a high speed, quantizes it into discrete levels, and outputs the corresponding digital value. The internal circuitry compares the input voltage with a reference voltage and iteratively adjusts the digital output until the conversion is complete.
