through my PIC i have wired up a 6bit R2R ladder on 5v, i have an opamp fed with 30 volts on +, i would like for the output of my circuit to be able to step from 0-30 vdc, i have gotten this circuit to work ok in multisim but i have not been able to reproduce, is multisim accurate on my circuit operation? am i using proper circuit for this? ect...
the amp i actually used was LT1363
my value for R is 10k (20k=2R)
i realize the steps are non linear in sim, since the switching sequence viewed was 1,11,111,1111,11111,111111,
essentially i want the output at 6x input
