What is the major advantage of the R/2R ladder digital-to-analog (DAC), as compared to a binary-weighted digital-to-analog DAC converter?

It has fewer parts for the same number of inputs.

It only uses two different resistor values.

Its operation is much easier to analyze.

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