Working Principles

The AD7666ACPZRL operates by sampling the analog input signal and converting it into a digital representation using its internal ADC circuitry. The analog signal is first conditioned and amplified, then fed into the ADC. The ADC converts the analog signal into a binary code, which is then transmitted through the serial interface for further processing or storage.
