Most Op Amps applications are inherently PSU-ripple insensitive.

They are a design from Elliot Sound Products. But the published

doesn't show the supply rail side of the design. You have to buy the

to see it.


Assuming that Fredxx has the right link, I think that you should take
it with a little pinch of salt.Â* An article originated 2000,
referring to a 50+ year old Op Amp design (great advance though it
was) is the first hint.

I'm struggling to see this phrase. A word search finds 3 'year's as
part of 2 'many years" and one "over the years". A search of '50'
finds 4, none of which pertain to time.

FAOD the article was revamped in 2021. Perhaps they frequent this
newsgroup and updated it in the past day or so? Rod? No, he claims to
be a chemist.

Perhaps Rod Speed is AKA Rod Elliott?


Or Russ Andrews !
