 (dĭj′ĭ-tl-tə-ăn′ə-lôg′, -lŏg′)
n. Abbr. DAC
A device that converts a digital signal into an analog signal, especially into an electrical signal whose voltage reflects the digital values. Digital-to-analog converters are commonly used to convert digital media for playback on analog devices, such as speakers, headphones, and older televisions. Also called D/A converter.
