![]() Some of the important applications are discussed below. In this way, we can find that when the input data is b3b2b1b0 (where individual bits are either 0 or 1), then the output voltage isĪpplications of Digital to Analog ConverterĭACs are used in many digital signal processing applications and many more applications. The output voltage is V0=3R(i0/16) = Vref/16 The output voltage is V0=3R(i1/8)= Vref/8įinally, the circuit is shown in below corresponding to the case where b0=1 and b2=b3=b1=0. If b1=1 and b2=b3=b0=0, then the circuit shown in the figure below it is a simplified form of the above DAC circuit. Similarly, If b2=1, and b3=b1=b0=0, then the output voltage is V0=3R(i2/4)=Vref/4 and the circuit is simplified as below The output voltage is V0=3R(i3/2)= Vref/2 Let the binary value B3 B2 B1 B0, if b3=1, b2=b1=b0=0, then the circuit is shown in the figure below it is a simplified form of the above DAC circuit. In order to achieve high-level accuracy, we have chosen the resistor values as R and 2R. ![]() The above figure shows the 4-bit R-2R ladder DAC. R-2R Ladder Digital to Analog Converter (DAC) ![]()
