Working Principles

The ADC0838CCN utilizes the successive approximation technique to convert analog signals into digital form. It samples the analog input voltage, compares it with a reference voltage, and generates an 8-bit digital output representing the input voltage level.

The conversion process involves a series of approximations, where the ADC successively sets and compares the most significant bit (MSB) to determine the digital output value. This iterative process continues until all 8 bits are determined, resulting in a digital representation of the analog input.
