Interfacing to the Analog World
What is the major advantage of the R/2R ladder D/A converter as compared to a binary-weighted D/A converter?
It has fewer parts for the same number of inputs.
It is much easier to analyze its operation.
It uses only two different resistor values.
The virtual ground is eliminated and the circuit is therefore easier to understand and troubleshoot.
Correct Answer:
It uses only two different resistor values.
