Working Principles

The AD2S1210ASTZ operates based on the principle of successive approximation. It converts analog signals into digital data by comparing the input voltage with a reference voltage and iteratively adjusting the digital output until it matches the analog input within the desired resolution.

The device utilizes an on-chip programmable sinusoidal oscillator to generate an excitation signal, which is applied to the input signal. The resulting analog signal is then converted into digital data using the internal ADC circuitry. The digital data can be accessed through the serial interface for further processing or analysis.
