Ladder Network
Lets assume all the binary inputs are grounded at 0 volts, that is: V
A = V
B = V
C = V
D = 0V (LOW). The binary code corresponding to these four inputs will therefore be: 0000. Resistors
R1 and
R2 are in \u201cparallel\u201d with each other but in \u201cseries\u201d with resistor
R3.

The R-2R Ladder DAC overcomes the disadvantages of a binary weighted resistor DAC. As the name suggests, R-2R Ladder DAC produces an analog output, which is almost equal to the digital (binary) input by using a R-2R ladder network in the inverting adder circuit.
