Working Principles

The ADC08832IWM/NOPB operates on the principle of successive approximation. It converts analog signals into digital data by comparing the input voltage to a reference voltage and determining the closest digital value. The conversion process involves a series of approximations, where the ADC successively adjusts its internal digital-to-analog converter (DAC) to match the input voltage. The final digital value represents the closest approximation to the original analog signal.
