Working Principles

The ADS8402IPFBTG4 operates based on the successive approximation register (SAR) architecture. It converts analog signals into digital data by comparing the input voltage with a reference voltage and iteratively approximating the digital representation.

1. The analog input voltage is sampled and held.
2. The internal SAR circuitry compares the sampled voltage with the reference voltage.
3. The ADC iteratively adjusts the digital representation of the input voltage until it converges to the closest digital value.
4. The resulting digital data is then output through the serial interface.
