In electronics, a digital-to-analog converter (
DAC,
D/A,
D2A or D-to-A) is a
function that converts digital data (usually binary) into an analog signal (current, voltage, or electric charge). An analog-to-digital converter (
ADC) performs the reverse function. Unlike analog signals, digital data can be transmitted, manipulated, and stored without degradation, albeit with more complex equipment. But a DAC is needed to convert the digital signal to analog to drive an earphone or loudspeaker amplifier in order to produce sound (analog air pressure waves).
DACs and their inverse, ADCs, are part of an enabling technology that has contributed greatly to the digital revolution.
