What is the major advantage of the R/2R ladder DAC as compared to a binary-weighted-input DAC?
A) The virtual ground is eliminated and the circuit is therefore easier to understand and troubleshoot.
B) It uses only two different resistor values.
C) It is much easier to analyze its operation.
D) It has fewer parts for the same number of inputs.
Question 2
