What is the major advantage of the R/2R ladder DAC as compared to a binary-weighted-input DAC?

The virtual ground is eliminated and the circuit is therefore easier to understand and troubleshoot.

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.
