In this video, R-2R ladder type Digital to Analog Converter has been explained with a solved example. • By watching this video, you will learn the following topics: • 0:23 Advantages of R-2R ladder DAC • 1:58 Calculation of the output impedance of R-2R ladder Network • 3:47 Calculation of the Output Voltage of 3 -bit R-2R ladder network • 15:35 Solved Example • R-2R Ladder DAC • By using the R-2R ladder network this type of DAC is designed. • As this DAC is using only two types of the resistor (R and 2R), it has certain advantages over Binary Weighted Resistor DAC • Advantages of R-2R ladder DAC: • 1) Uses only two values of Resistors • Easy and accurate fabrication is possible • 2) Easily scalable to any desired number of bits • 3) Output impedance is R, regardless of the number of bits • Commercially this type of DAC is available starting from 6-bit to 20-bit. • In this video, the calculation of 3-bit DAC is explained in detail. And using the same method it is possible to find the output for n-bit DAC. • Check out the other useful videos related to ADC and DAC: • 1.
