That AD8605 isn't bad, low noise and reasonable input capacitance.
But the AD8033 (jfet) has it beat on most specs: 8x the bandwidth, less than half the Cin, and up to 24 volt supplies. It seems to be absolutely c-load stable.
Digital CMOS is of course a different issue. I can't imagine a bipolar (or jfet!) FPGA. There were some attempts at doing logic with gaasfets (Gigabit Logic!) but that didn't work out.

I was trying to get Jim to back up his claim about how fast linear CMOS can be. I asked him to cite some fast CMOS opamps. That would actually be on-topic and useful to the group. His response is to insult and then killfile me (for, maybe, the 10th time!)
Wrong. I named opamps, by part number. He didn't. Because he's factually wrong.

Read the thread. What I've been slinging is opamp part numbers.
-- John Larkin Highland Technology Inc www.highlandtechnology.com jlarkin at highlandtechnology dot com Precision electronic instrumentation
I am happy to compare opamps. But he won't play.

-- You really didn't; what you _wanted to do was to best Jim at his own game by changing the focus of the thread to fall into line with what you considered to be an area where you'd be unbeatable.

-- I agree. My feeling is that Larkin starts the mudslinging much more often than Thompson does, though, since all Jim has to do is post something - even something innocuous - and John is all over him. But maybe that's just me...
-- No, you weren't. What you were trying to do was to get him to post_anything_ so that you could counter with something faster in bipolar and continue your neverending harangue.
-- And derision. And misinformation. And taunts. And on. And on... John Fields
-- Perhaps he doesn't like rolling around in the dirt as much as you do.

So, you wouldn't mind if people slagged your wife?
-- John Larkin Highland Technology Inc www.highlandtechnology.com jlarkin at highlandtechnology dot com Precision electronic instrumentation
So you concede that bipolar opamps are faster than cmos opamps? Thanks for backing me up on that. Too bad Jim can't see it.

What an imagination you have.
Jealousy will get you no where!

-- Actually, it's not something I concern myself with since I don't have the kind of wife anyone would want to slag. John Fields
-- Not at all, since some are and some aren't.

That was just mildly off-color humor in the context, you blew it up into a silly pistols-at-dawn mortal insult thing.
But I do think Jim is almost always to blame for the "fights".
