LM324 mixer?
« on: August 21, 2009, 03:20:28 AM »
I have an LM324N IC and I was wondering if there is any way I can make a small mixer out of it. I have the datasheet here http://www.national.com/ds/LM/LM324.pdf and it says inputs and output(s) but I don't know anything about making stuff like this.

Thats a quad op-amp, which is exactly the same as the single op-amp version of that chip, only with 4 of them.

You could concievably use it as part of a mixer circuit but its not going to do anything useful on its own, and its probably overkill for a simple mixer.

The mixer circuit below uses an LM837 which is also a quad op-amp but it only uses one of the opamps,.



You should really do some reading on basic electronics before you attempt stuff like this. It'll really help in the long run.

It will probably work... I've never tried it is all. I had a stash of TL074s when I was working on the Klee,so the part pretty much chose itself. Give it a whirl..I'd be interested to know if it works or not.
