Working Principles

The ADC0820CCN utilizes successive approximation technique to convert analog signals into digital data. It samples the analog input voltage and compares it with a reference voltage using an internal comparator. Based on the comparison result, the converter adjusts its internal digital-to-analog converter (DAC) to approximate the input voltage. This process is repeated iteratively until the digital output accurately represents the analog input.
