Thanks for the reply akg,
Yes, that is my intention, so it will not overload the non inverting amp, and so that it will not be so much to remove the offset later. What I'm wondering, though, is if that is too much attenuation? I have reduced the 100k to 60k, and increased the 560ohm to as much as a few k, with no noticible improvements. I think it did quiet down a bit too, when I added a small cap in paralell with the 560 ohm. I'm going to try increasing the value of that cap, and see what happens.
A big part of the problem is my limited analog knowlege, but I'm changing that now. :cry:
Regards,
Robert
