Working Principles

The ADS8326IBDRBR is an analog-to-digital converter that operates based on the successive approximation technique. It converts continuous analog signals into discrete digital data by comparing the input voltage with a reference voltage and determining the closest digital representation. The conversion process is controlled by the internal circuitry, which includes a sample-and-hold amplifier, a comparator, and a successive approximation register (SAR).
