Copy of R2R digtal analog converter 8bit

R-2R resistor network Digital -> analog converter This example will explain the funktion and you can develop the rules easily: 4bit Uref =16V 4bit Results: Ustep =1V Umax =15 V Umax = Uref - Ustep Ustep = Uref/2exp4 8bit Uref =2.56V 8bit Results: Ustep =0.1V Umax =2.55 V Umax = Uref - Ustep Ustep = Uref/2exp8
