R 2r Ladder Dac Circuit Diagram. One of them is R-2R DAC. The R-2R Ladder DAC overcomes the disadvantages of a binary weighted resistor DAC.
It covers weighted resistor DAC R-2R inverting ladder DAC R-2R non-inverting ladder DAC etc. B1 B0 The typical value of feedback resistor is. Digital to Analog Converter with R and 2R Resistors Resultant Circuit.
For implementing R-2R DAC we require only two different values of resistors one is R and other is 2R.
There are probably more that you can use it for. Digital to Analog Converter with R and 2R Resistors Graph. So we can replace that entire resistor network with a single resistor having resistance of 2ROmega. Current through 2R connected to 5V 5V20kohm 025 mA.
