How to generate a fixed differential voltage dependant on a voltage relative to ground? Answered
What methods can I use to generate an accurate & precise variable differential voltage that's dependant on the output of a +-10V DAC?
I tried to use a resistor with a small variable current sink using the classic opamp+NPN design, but no design I made would sink current below 1V. I need it to continue sinking current down to 0V, I do have a negative supply rail avalible.
(I think my last question was a bit TL;DR for some, so this is a shortened version of that.)
