Since digital signal consists of 1’s and 0’s, the variations supported will be 2 to the power of “n-bits”. Resolution: this is the number of variations that the Digital to Analog Converter is capable of generation and is usually stated as the number of bits it supports.Here are some parameters that we can refer to when looking at a Digital to Analog Converter: NOS Digital to Analog Converter does not have the best specifications on paper but the sound tells another story.
The NOS Digital to Analog Converter camp focus on the sound for example the Philips TDA1541, TDA1543, TDA1545 Digital to Analog Converter chips, are liked by a lot of audiophiles over the tonality it possesses. The high performance camp chasses the highest resolution, THD+N, DNR, Dynamic Range, and etc. There are 2 camps actually, the high resolution high performance versus the NOS (non over-sampling) camp. What do we look for when we choose D.A.C.s? Although specifications are very important, it is not the only criteria to determine the superiority of the D.A.C.s. D.A.C.s can also be found in high end HIFI systems, as standalone equipment dedicated just to convert digital signal to analog audio signal. One of the applications for Digital to Analog Converter is to convert digital into analog audio signal, and therefore it fits as a topic in Audio signal, by nature, is analog signal and it needs to be converted to digital signal by an ADC, analog-to-digital convert (A-to-D), which is a reverse function of Digital to Analog Converter.ĭ.A.C.s are usually contained in CD players, digital music players, PC sound cards, cell phones, home theater receivers, and etc. The function of the Digital to Analog Converter is to convert the 1’s and 0’s into analog signals. Analog signals are stored digital format as 1’s and 0’s.
It is a device that converts digital code to analog signal. DAC, is also called a digital-to-analog converter (D-to-A).
