Working Principles

The AD7575JN operates on the principle of successive approximation. It samples the analog input voltage and compares it to a reference voltage. The converter then generates a digital output code that represents the input voltage with a resolution of 12 bits. This process is repeated at a high sampling rate, allowing for real-time conversion of analog signals into digital data.
