Working Principles

The AD977ARSZ is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a combination of sampling and quantization techniques to achieve this conversion. The input analog signal is sampled at a high rate, and each sample is then quantized into a corresponding digital value. The resolution of the ADC determines the number of possible digital values, with higher resolutions providing more precise representation of the input signal.
