Re: 627 is a VFB, unity gain compensated device

61.12.128.6

Hi WMS

I found same with 627/637. Did you bias OP into class A,
this is definately worthwhile.
What other devices did you compare to?
I missed the first part of message, I assume you were
reffering to 627 with BUF634 inside loop.
Did you run 634 in wide BW mode as is recommended?
