The audio signal is analog in nature but it is converted using ADC (analog to digital converter) into digital format to edit & store in storage devices in various digital formats such as mp3, wav etc. ![]() Some of the various applications of a DAC are given below Audio: Counter and Different Types of Electronic Countersĭigital to analog converters are used in various applications to convert a digitally processed signal into an analog signal.Increasing the resolution of a DAC decreases the step size & generates a smooth analog wave with much more accuracy. So for a single bit increment, its analog output will increase by 0.3125 v. ![]() The step size can be calculated by dividing the range (maximum output voltage) or V ref by 2 n where n is the number of bits.įor example, the step size of a 4 bit DAC with range of 5v is The step size of a DAC is the smallest change in the analog output & it is the difference between two consecutive output voltage levels. For example, a 4-bit DAC has resolution of 2 4 or 16 output levels. Resolution is the number of possible output levels a DAC can produce. Resolution & step size of a DAC plays important role in the precision & accuracy of the analog output. Resolution & Step Size of Digital to Analog Converter
