Looking for a small Op-Amp board

audiosteve · 15th February 2009, 08:09 PM

Hello all,

I have searched the forum to find this, which makes me think it may not exist.

Does anyone know where I can find a SMALL simple PCB that is laid out simply to allow placement of a dual-channel op-amp with necessary gain and input R's and bypass and coupling caps. I need a few non inverting stereo buffers for a project.
Any help on this would be GREATLY appreciated.

Thanks much

Check out the DEM-OPA-SO-2A from TI.

Thanks Richard! That is exactly the kind of thing I am looking for.But this will be my first foray into surface mount soldering. Hopefully I'll do OK.

I have some opamp PCB's here if they suit you:
SS Power Supply and generic opamp PCB.

Cheers!

Thanks geek but those boards are layed out for for single ended supply so don't fit my application. But I appreciate the notice.

Try Radio Shack they have a small board that you can solder Op Amps to. I've used them for a number of projects.

I still have these.......

FS: Mini headamp/preamp/buffer boards

How many do you need? I'm very negotiable on the price. I Don't know if I still have all the op-amps mentioned in the post.
