Hi, thanks for the reply, the diagraim was presented that way for me to do the calculations, i have also seen related diagraim online for DAC!berkeman said:That doesn't look right to me. You also can't get 10V out if the power supplies are +/-9V.
Are you trying to make an R2R ladder DAC?
berkeman said:Well, can you explain this first line from your diagram? It doesn't make sense past the 900mV number...
Vout = (9V x 470/4700) = 900mV = 800mV = 8V
And why are the resistor values in your table different from the schematic?
