These two applications use DACs at opposite ends of the frequency/resolution trade-off. They are also used in televisions and mobile phones to convert digital video data into analog video signals.
Digital-to-analog conversion can degrade a signal, so a DAC should be specified that has insignificant errors in terms of the application.ĭACs are commonly used in music players to convert digital data streams into analog audio signals. There are several DAC architectures the suitability of a DAC for a particular application is determined by figures of merit including: resolution, maximum sampling frequency and others.
An analog-to-digital converter (ADC) performs the reverse function. In electronics, a digital-to-analog converter ( DAC, D/A, D2A, or D-to-A) is a system that converts a digital signal into an analog signal. 8-channel Cirrus Logic CS4382 digital-to-analog converter as used in a sound card.
