duel op amp power supply assymetry tolerance
I bought a linear +/- 12v power supply for my active crossover. It measures +12.06 / -11.86. Is this acceptable for powering the opamps, I have no reference point as to how close the rails must be to eachother. I would believe that the feedback path on all the amps would make up for any dc offset. I'd rather not build a power supply, as I already have a lot of stuff to make.
Thanks, Lee |

LOL that's fine. A worst case rail tolerance of 1.17%
