I found this article (http://pdfserv.maxim-ic.com/en/an/AN656.pdf), which I think is on target with what you suggested. I might try the "conversion" that is represented by the differences in these circuits: http://focus.ti.com/lit/an/sloa093/sloa093.pdf Thanks for your insight...I'll let...

Ah...interesting. I am running 0 to +12 volts supply. I'll try the split voltage trick tonight. I'm not too sharp on this, what is the input Vcm?

OH...and the Digi-key stock might be a good idea. I'll let you know when I get home tonight!

Good questions: In this case I'm using the dual op-amps in the 8-pin package. I should have said the OPA2228 for the TI op-amp. Input resistors are 5k, feedback resistor is 10k.

I would appreciate some practical advice on a problem I'm having with a project I'm working on. I have implemented a simple voltage adding circuit using an op-amp. (see http://homepages.which.net/~paul.hills/Circuits/Adder/Adder.html for the generic circuit) Using one amp of a LM348...
