Digital-to-Analog Converter (DAC)

A Digital-to-Analog Converter (DAC) is a device that transforms digital data, which is composed of discrete numbers (like 0s and 1s), into continuous physical signals, typically electrical voltage or current. This process is essential for devices like audio players and computers to produce real-world sounds or visuals. The DAC takes the digital information and reconstructs a smooth, variable signal that can drive speakers, screens, or other analog equipment, enabling digital technology to interact seamlessly with the analog physical environment.
