An R-2R ladder type DAC is shown below. If a switch is ‘0’, 0V is applied and if a switch is ‘1’, 5 V is applied to the corresponding terminal of the DAC.
What is the output voltage (V0) for the switch status S0 = 0, S1 = 1, S2 = 1?1
\(\frac{5}{4}\;V\)
2
\(\frac{{15}}{4}\;V\)
3
\(\frac{{17.5}}{4}\;V\)
4
\(\frac{{22.5}}{4}\;V\)
