Greetings, We built an R2R DAC. Later I found the schematic at https://www.digilentinc.com/Data/Products/PMOD-R2R/PmodR2R_sch.pdf. My question is: Should the 200 Ohm internal resistors going in to the PMODs figure in the R2R values. We used 1.8k and 1k resistors, figuring on including the 200 Ohm resistors to make 2k. The pdf schematic above uses 10k and 20k resistors. Any comments? Opinions? Thanks, John
