Is an electronic circuit or device that translates digital information (binary codes of 1s and 0s) into a continuous analog signal, such as voltage or current. Because our physical world is analog, DACs are the essential bridges that allow digital devices to generate sound, light, and motion.
Digital Input: The device receives a sequence of binary numbers, which represent discrete steps in an audio or video signal.Conversion: Using internal networks of precisely matched resistors or capacitors (like an R-2R ladder), the DAC assigns proportional weights to each binary bit.Analog Output: It outputs a continuously fluctuating voltage or current that corresponds to the inputted binary data
