It uses a successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input voltage is compared against a reference voltage, and the converter iteratively approximates the digital representation of the input voltage until a desired level of accuracy is achieved. The converted digital data is then made available through the serial interface for further processing.
