[sdiy] Using Opamps as INV or NON-INV amplifiers

[Dave Kendall]

Hi Guys.

Apart from the gain being minimum of 1 for a non-inverting amp, are there
any other advantages or gotchas about using one form or another? There's
lots of stuff about op-amps out there, but I'm still a bit unsure about the
practical differences in use. It would seem that a single NON INV amp is
easier to implement, and yet often the INV configuration is used, with a
second re-inverting stage ...

Any thoughts welcome.

cheers,

Dave (still coming to terms with the impedance monster ;-)
