Almost all opamp circuits you will ever need (with formula’s)

Pt 18

Just stumbled on this application note from National Semiconductor. It’s a nice summary of standard opamp circuits with formula’s. I thought it would be a nice item for the blog.

  1. Great bit of an app note. I wanted to point out that the LM394 is officially obsolete though. It’s still possible to find them and they’re really great parts, but I’d be careful if people plan on designing them in.

  2. It’s not LM394 specific at all, the schematics work for any opamp, just check the pinout in the datasheet of the opamp you’re using.

  3. -> with formulas
    (or even more correct, formulae)
    (sorry to be one of those people)

    that is a fantastic cookbook, the kind of
    thing that made national so much more than
    a chip manufacturer… community building is the way to go.

    the matched transistor circuits still blow my mind.
