Hi,

You should be more specific on your needs.

If you make a google.com search with the words: audio amplifier circuit , then you will find more than 100000 URLs dealing with your request. Good luck!

This is audio band so you can use any audio amp, simpliest is TDA200x series. There are lot of integrated audio amps, but you don't define all parametars so I can't recommend you any specific circuit. If you want some circuit which is with no integrated amps pm to me and I send you schematics.

Regards!

Hello:

If you're not looking for anything TOO sophisticated, the chip amps available from National Semiconductor and ST Microelectronics are a safe bet. They usually have app notes to go with them that'd help you get to something functional in short order. Some are even parallelable, (National has an app note on this) for increasing power output.
