lm 358 ic - connection

can anybody tell me exactly how to connect an 8 pin Lm 358 ic?, in other words EG : pin 1 = _+DCV IN pin 2 = _GROUND_ pin 3 = _-DCV OUT_ etc? .

and while you are at it explain waht is inverting and non inverting inputs and outputs ?

Firstly, the mandatory link to the IC's page: http://www.national.com/mpf/LM/LM358.html which shows you the pinout of the IM358.

Secondly the mandatory link to a page explaining the basics of Op Amp usage http://web.telia.com/~u85920178/begin/opamp00.htm which will help you understand how they should be put into a circuit.

And lastly, i'm not an expert on op amps by any means, but from what I've read it's generally best to use inverted output due to signal noise issues you can get with non-inverted output. Basically all it does is invert the waveform from the input for the output.

Hope that helps some. :)
