![]() Very high speed test equipment, especially sampling oscilloscopes, may also use discrete DACs. Discrete DACs would typically be extremely high speed low resolution power hungry types, as used in military radar systems. The audio DAC is a low speed high resolution type while the video DAC is a high speed low to medium resolution type. These two applications use DACs at opposite ends of the speed/resolution trade- off. They are also used in televisions and mobile phones to convert digital video data into analog video signals which connect to the screen drivers to display monochrome or color images. DACs are commonly used in music players to convert digital data streams into analog audio signals. Digital- to- analog conversion can degrade a signal, so a DAC should be specified that has insignificant errors in terms of the application. There are several DAC architectures the suitability of a DAC for a particular application is determined by six main parameters: physical size, power consumption, resolution, maximum sampling frequency, accuracy and cost. ![]() ![]() An analog- to- digital converter (ADC) performs the reverse function. In electronics, a digital- to- analog converter (DAC, D/A, D. Digital- to- analog converter - Wikipedia, the free encyclopedia. ![]()
