D-a-converter meaning

dēā
Short for digital to analog converter. An electronic device that takes a digital numerical value as input, and yields a voltage signal at the output proportional in strength to the value of the input. D/A converters are used in digital audio and video technology, in which audio or video information stored in digital form (as on tape or a disk) is converted to electrical voltage signals for amplification or display on a screen.

(Digital/Analog converter) A device that converts digital code into analog signals mostly for audio. D/A converters (DACs) convert digital audio samples into the analog waveforms sent to audio amplifiers and speakers. A D/A converter (DAC), which may be a single chip or a circuit within a chip, is found on every device that sends analog speech or music to an amplifier, speaker or headphones, including computers, smartphones, tablets and A/V receivers. See DSP, codec, PCM and ladder DAC.Also for VideoEarlier TVs accepted only analog video, and converter boxes use DACs to convert digital TV broadcasts to analog (see TV converter box). See DTV.Stand-Alone Audio DACsAlso called "digital audio converters" or "outboard DACs," stand-alone DACs are used by audiophiles to convert digital audio from a CD/DVD player, cable box, local computer or the Internet to analog signals for amplification. Providing higher quality sound and higher digital resolutions than the DACs built into most equipment, stand-alone DACs range in price from USD $79 to several thousand (see USB DAC and high-resolution audio). Contrast with A/D converter.
