Working Principles

The AD976ARS is an analog-to-digital converter that operates based on the successive approximation technique. It converts continuous analog signals into discrete digital values by comparing the input voltage to a reference voltage and determining the closest digital representation.

The converter uses a parallel interface to receive the analog input voltage and clock signal. The internal circuitry then performs a series of comparisons and adjustments to approximate the input voltage. The resulting digital value is outputted through the parallel data lines.
