[FAQ] How do I ask a question on E2E?
I found an error in TIDU-December 2013-Revised December 2013, but I'm not sure how to report it.
So I'll just write it up here and hope it helps someone.
Tim Green's write-up is excellent, and this correction might be considered nit-picking.
In the section 5, modifications, the text says "For this single supply application, using OPA2376 dual op amp..."
I believe Tim's intention was to use one IC with two sections: U1a and U1b.
But the schematic indicates two separate IC's, U1 and U2, and the pin numbers wrong for the OPA2376.
The pin numbers correspond to the OPA192, which was used earlier in the document.
My guess is the recommendation to use the OPA2376 for single-rail applications was an afterthought, and that the schematic was only partially updated.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Tim Green1:
Thanks, Tim. That explains it.
While I've got you, my application is uses a single-ended +12VDC supply, so the OPA2376 probably isn't a solution.
Would you recommend the OPA192, or some other part?
(It would be great to have a quad device so that I could use one op-amp to buffer Vref.)
Btw, it's an honor to get a direct reply from the Great and Powerful Wizard of Zo!
