Gargletron IC?

[Arn C.]

Howdy All,
   I don't have a TL062, can any other IC's be substituted here?

Thanks!

I believe I used a TL082, but I'd think about any of the usual suspects would work in there. Like, TL072, 4558, and maybe a 5532, although the seem a lot more finicky.

Thanks a bunch JMUSSER!

Peace!

I'm just guessing here, but my gut says that a bi-fet is recommended, and a 5532 counter-indicated, if only because of the high feedback resistance (5M, 2.2M) used.

In terms of noise, a TL072 might be optimum.  The 062 is lower current consumption but somewhat noisier.  I can't speak to what would happen with a TL082 or "classier" type like an OP-275.

Thanks Mark!  I believe I am going to try the TL072 .  That is what I figured out in my cross reference book that the TL062 was low power consumption, but basically same as TL072.

Peace!
