Subject description: I need some help with the internal op-amps on the NE570
Reply with quote  Mark this post and the followings unread

I'm working on a project that uses the NE570. It's basically a panner that pans the two inputs and mixes them with one of the on-board op-amps.

The problem is that the op-amps in the NE570 seem only to be usable in the inverting mode. This leaves the out put of project inverted. Which sounds fine but might run into problems in the future.

The solution would be to run the output through an inverting op-amp set up as a follower. I don't want to add another chip, especially when one more op-amp in the NE570 that I haven't used. The problem is that I can't quite wrap my head around setting this. Can anyone point to example of something like this?

I have Mr Henry's excellent book on the 570. I would recommend this book to anyone using this chip. Easy to read with a lot of good info.
