Can someone provide an easy sine wave (audio) oscillator that doesn't need too many parts? (i.e. phase shift oscillator)

Also, can a Colpitts/Armstrong/Clapp circuit be used to generate audio tones? (Those above mentioned are usually used with RF circuits).

 

Use the FreqGen app on your iPod. It'll give you sine, square or triangle waves over the full audio spectrum.

Probably not what you were looking for, but you haven't explained why that wouldn't work.

 

Are you looking for an IC?

 

You may use some free software and your PC sound card for this job. Just a tip but anyway this book has a good oscillator section

This TI application note should get you what you want:

And also this National Semiconductor application note, also now on the TI website

You could use an XR2206 function generator chip. It will generate sine, triangle, and square-waves. The sine-wave does have a small amount of distortion so it's not suitable for high quality audio distortion measurements, if that's what you need.

 

So u need a basic version of oscillator. OKie so if u wanna try then go for any of these two circuits!!!!

If you just need a single frequency, try a Wien bridge oscillator:

\(\frac {Rf}{Rg} = 3
f= \frac 1{2 \pi RC}\)

 

If you just need a single frequency, try a Wien bridge oscillator:

The circuit you posted is extremely simple. It has nothing to control its output level. Its output will rise until the opamp is badly clipping with lots of distortion.

 

Exar XR-2206. I built a benchtop signal generator using it.
