Nor have I
The one I had to replace on my Nicolet oscilloscope
was made by
Lambda. I don't recall the reference voltage but I did have to change
the feedback resistors to get it to work.
I seem to remember that Lambda used a semi-custom IC that was the
same as a 723 in pinout and function, but had a different reference
voltage. Whether this was simply to make you get spares from them or
for some actually useful reason I don't know.
Was the failed IC marked '723' or some house number?
