Working Principles

The ADS8344EB/2K5 operates on the principle of successive approximation. It samples the analog input voltage and converts it into a digital representation using a series of comparisons. The internal circuitry compares the input voltage with a reference voltage and adjusts the output code accordingly. This process is repeated for each sample, resulting in a digital representation of the analog signal.
