Can anyone point me to a tutorial for electronic noobs that explains how to use op-amps and what I can do with them, besides amplification?

Hyperphysics has a pretty good section about opamps:

    \$\begingroup\$ Hyperphysics in general is made of multiple flavors of win, with a sprinkling of awesome and a dash of genius. Between that and wikipedia the first 2 years of college are pretty much covered. \$\endgroup\$ Apr 4 '12 at 15:34

  • \$\begingroup\$ @JoeStavitsky: Is there an overview/index page of Hyperphysics somewhere except the directory listing? \$\endgroup\$

I know it's not all online, but the Art of Electronic by Horowitz and Hill is fantastic. It's basically the only book you need for the first 2 years of learning electronics (especially if you don't have any math requirements). The second edition of the book was published back in the late 80s and a lot of the example circuits using op amps are spectacular examples.

  • \$\begingroup\$ As someone in "the first two years of learning electronics", I must say that it's not necessarily for beginners. Some people may grasp it intuitively, but for the rest of us it's a concise reference. \$\endgroup\$ Apr 4 '12 at 15:32

Try Opamps for Everyone (warning -- large pdf, and some TI bias)

It has lots to teach, covers beginning to somewhat advanced topics, and it's free.

There are a couple of very good tutorials at Analog Devices and Texas Instruments. The TI one is called "Handbook of Operational Amplifiers".

Op amp Cookbook

This book is considered to be a key text on the subject. I dont think there is an online version available... £30 (where I come from) is around the "reasonable" price range for such books.

  • \$\begingroup\$ I will add my vote. It can be found on abebooks as well. Excellent book, covers how to do all manner of analog math with op-amps. Linearization, converting linear to logarithmic, etc. \$\endgroup\$ Dec 7 '09 at 1:38

Falstad Falstad Circuit index has an excellent Java applet that allows you to do virtual prototyping with various types of circuits.

Has a nice section on Op amps, whats great is the built in O'scope, volt and current meters. Right clicking on a template component in the applet brings up menu where you can experiment/substitute with different values, add remove components.

This one helped me a lot for a Devices class which included op-amps. Really good animations, and covers most types (inverter, differentiator...) needed for a starting point.[link text]

I always simulate my op amp and other analogue circuits with SPICE before building and testing them. Free SPICE implementations are available, and many PCB packages include it.

    \$\begingroup\$ It's no use simulating if you don't know how to use them. \$\endgroup\$ Jun 11 '11 at 15:16
  • \$\begingroup\$ Why the downvote? It helps one learn how to use them without wasting time building hardware that doesn't work. SPICE packages generally have plenty of examples of op amp circuits. \$\endgroup\$ Jun 11 '11 at 16:18

The "IC Opamp Cookbook" paperback was ~THE~ standard for hobbyist electronics back in the 80s. Still a good reference.

Op Amps for Everyone (2.0 MB PDF) by Texas Instruments is a very good reference. It covers almost any aspect you might need. Even single supply opamp techniques.
