Working Principles

The ADC12DL040CIVS/NOPB operates based on the successive approximation register (SAR) architecture. It samples the analog input voltage, converts it into a digital representation using a comparator and a digital-to-analog converter (DAC), and provides the converted digital data through the serial interface.

The device utilizes an internal clock to control the conversion process. The analog input voltage is compared to a reference voltage, and the comparator determines the most significant bit (MSB) of the digital output. The DAC then adjusts the analog input voltage based on the comparison result, and the process repeats for each subsequent bit until the desired resolution is achieved.
