Video sampling tends to work on a completely different scale altogether thanks to the highly nonlinear response both of cathode ray tubes (for which the vast majority of digital video foundation work was targeted) and the human eye, using a 'gamma curve' to provide an appearance of evenly distributed brightness steps across the display's full dynamic range - hence the need to use RAMDACs in computer video applications with deep enough color resolution to make engineering a hardcoded value into the DAC for each output level of each channel impractical (e.g. In voiceР Р†Р вЂљРІР‚В¦overР Р†Р вЂљРІР‚В¦IP applications, the source must first be digitized for transmission, so it undergoes conversion via an ADC and is then reconstructed into analog using a DAC on the receiving party's end.

Similar digital-to-analog converters can be found in digitalР Р†Р вЂљРІР‚В¦speakers such as USB speakers, and in soundР Р†Р вЂљРІР‚В¦cards. These normally take the digital output of a compatible CDР Р†Р вЂљРІР‚В¦player or dedicated transport (which is basically a CD player with no internal DAC) and convert the signal into an analog line-level output that can then be fed into an amplifier to drive speakers. Specialist standalone DACs can also be found in high-end hi-fi systems.

DACs are therefore found in CDР Р†Р вЂљРІР‚В¦players, digitalР Р†Р вЂљРІР‚В¦musicР Р†Р вЂљРІР‚В¦players, and PC soundР Р†Р вЂљРІР‚В¦cards. Most modern audio signals are stored in digital form (for example MP3s and CDs) and, in order to be heard through speakers, they must be converted into an analog signal. Top-loading CD player and external digital-to-analog converter. Very high-speed test equipment, especially sampling oscilloscopes, may also use discrete DACs.

These typically take the form of metalР Р†Р вЂљРІР‚СљoxideР Р†Р вЂљРІР‚Сљsemiconductor (MOS) mixed-signalР Р†Р вЂљРІР‚В¦integratedР Р†Р вЂљРІР‚В¦circuit chips that integrate both analog and digitalР Р†Р вЂљРІР‚В¦circuits.Р вЂќР’Вiscrete DACs (circuits constructed from multiple discrete electronicР Р†Р вЂљРІР‚В¦components instead of a packaged IC) would typically be extremely high-speed low-resolution power-hungry types, as used in military radar systems. The audio DAC is a low-frequency, high-resolution type while the video DAC is a high-frequency low- to medium-resolution type.Р вЂќР’Вue to the complexity and the need for precisely matched components, all but the most specialized DACs are implemented as integratedР Р†Р вЂљРІР‚В¦circuits (ICs). These two applications use DACs at opposite ends of the frequency/resolution trade-off. They are also used in televisions and mobileР Р†Р вЂљРІР‚В¦phones to convert digital video data into analogР Р†Р вЂљРІР‚В¦videoР Р†Р вЂљРІР‚В¦signals. Digital-to-analog conversion can degrade a signal, so a DAC should be specified that has insignificant errors in terms of the application.Р вЂќР’ВACs are commonly used in musicР Р†Р вЂљРІР‚В¦players to convert digital data streams into analog audioР Р†Р вЂљРІР‚В¦signals. There are several DAC architectures the suitability of a DAC for a particular application is determined by figuresР Р†Р вЂљРІР‚В¦ofР Р†Р вЂљРІР‚В¦merit including: resolution, maximum samplingР Р†Р вЂљРІР‚В¦frequency and others.

An analog-to-digitalР Р†Р вЂљРІР‚В¦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 digitalР Р†Р вЂљРІР‚В¦signal into an analogР Р†Р вЂљРІР‚В¦signal. 8-channel CirrusР Р†Р вЂљРІР‚В¦Logic CS4382 digital-to-analog converter as used in a soundР Р†Р вЂљРІР‚В¦card.
