Gene, I am not very experienced in discrete DACs. I know that you
have made some already. What I need is a precise 7-bit DAC,
because I have to cover at least -1V to +5V (so a 6-bit isn't enough).
What I fear is the temperature drift of the buffers impedance that
might be different from the external resistors' drift.
Would You suggest a discret R/2R ladder or just 7 different summing
