Hi, everyone.

I need recommendations for an audio operational amplifier, that works with a single power supply 5.0 Volts.
The idea is change the wave as little as possible.

Thanks for any help.

Pedro.

A plain old, typical, industry-standard NE5532 can work, much like a lot of other opamps, but it all comes down to what kind of circuit and application you have in mind.

Get a Linear Tech databook. They have opamps in there that border on science fiction.

Hi, this is for a Spektrum Analyser using a FFT Transform.

The MCP602x family are good for this type application.

I also like the Burr-Brown OPA series - very solid, at least back when I played with such things.
