Hi all (and especially carlosfm),

I'm thinking to build a buffered IGC amp.

Carlos' OPA627 buffer is on my list now. But I found that OPA627 is very expensive.

Can I use AD843 instead of OPA 627?

Carlos, I read that you say AD843 is a good replacement for OPA604. How about to use 2604 for GC buffer (since I have some 2604 on my stock)?

Thanks,
