A Digital to Analog Converter (DAC) is an electronic device that transforms digital signals, which are represented in binary code, into analog signals. These analog signals can be used to drive speakers, televisions, and other devices that require continuous waveforms. DACs are essential in various applications, including audio playback and video processing. DACs work by interpreting the digital data and producing a corresponding voltage or current that represents the original signal. This process allows digital devices, such as computers and smartphones, to communicate with analog systems, ensuring that users can experience sound and visuals in a way that is natural and enjoyable.
