DAC (Digital-to-Analog Converter)

A Digital-to-Analog Converter (DAC) is a device that transforms digital data, typically binary numbers used by computers, into analog signals that we can hear or see, like sound waves or video. For instance, when you play a song on your smartphone, the DAC converts the digital audio file into electrical signals that drive your headphones, producing sound. Essentially, it bridges the gap between the digital world, which computers understand, and the analog world, which humans perceive through senses. DACs are vital in various technologies, including audio equipment, televisions, and smartphones.
