    I am trying to build a circuit on an existing design that calls for an
    op-amp MC34071AP but this op-amp seems hard to find and not sold in
    small quantites, at most I only need 4. If anyone knows a good source
    for it or can recommend a replacement op-amp with very similar
    properties it would be appreciated.

    What's the design ? Is it a secret ?

    From TI, TL071

    Or substitute MC34081 -82, -84, or TL081

    There is the TI TL3472 which is a duplicate design with slight variation
    in some of the max ratings, probably more realistic, and available in
    small quantities from Mouser.

    Oooops! Looks I remembered incorrectly :-(

    TL071 is just a poorer spec'd version of TL081 which is the same as
    MOTO's MC34081

    So I did a boo boo and extrapolated MC34071 to TL071, etc :-(

    Where on earth did you get a hare-brained idea like that ?

    Motorola were never able to make a decent bifet op-amp to save themselves.

    Thanks, im going to get one of those and see if it works for me.

    What!? Huh? Has ON Semi discontinued all their
    JFET opamps? Sheesh, stick with TI.
  11. Actually I think it's the other way round.
