Working Principles

The CS4340-CZZ is an analog-to-digital converter (ADC) that converts continuous analog signals into discrete digital values. It operates based on the principle of sampling and quantization. The analog input voltage is sampled at a high frequency by the internal clock, and each sample is then quantized into a digital value using a 12-bit resolution. The resulting digital output represents an approximation of the original analog signal.
