How to increase gain on a KA2206 power amplifier?

07-04-2008, 03:57 PM

I'm building a small amp with KA2206. Basically it works, but it's too quiet. How can I increase the gain on it. I know there are gain pins on other amps but I can't seem to find them on this one.

Hi.

What exactly is a KA2206? Oh, never mind, I just googled it.

It is a dual power amp IC. the input sections of each channel are just op amps, and like any op amp, the gain of the stage is determined by the resistors in its feedback loop. Download the KA2206 data sheet and there are application/testing notes on setting the gain.
