Quick electronic question
I need a 20k R2R resistor network (for making another project on the net) and I'm ordering from mouser and the only ones they have are out of stock, so I want to build one. I know how to hook the resistors relative to one another (a quick look at wikipedia solved that), the only thing I'm wondering about it the values... To make a 20k R2R network do I need:
10k and 20k resistors?
20k and 40k resistors?
I think it's 10k and 20k, but I'm not sure
