Master op amp substitution?

Discuss Yocto construction and related issues
  • Hi sorry to revive an old tread, but i have an opa1612 laying around, should i pop it in there?
    Also, is it a drop in replacement or will i have to add/ remove anything?

    Try it! This would be a drop-in replacement.

    Looking over the datasheets, you may get better noise performance with the OPA1612 compared to the stock OpAmp. The input offset current values aren't great compared to a JFET-input OpAmp like the TL072, but the noise figures are definitely better. I have not done a complete analysis to determine what figures matter most in this particular case, but let us know the results of your experiment!
