There seems to be no price cap on AD components! Solid stuff at a range of prices. It's sometimes tough to tell what makes the super-expensive ones different. Might be a little extra precision (etc) that's justified in niche cases.
I'd say volume. These are highly specialized devices which require a lot of careful development. The volume might be a few thousand a year if even. So seeing super high speed/precision ADC's costing 1000+USD isn't so surprising.
that's interesting, ADI doesn't even list it anymore on their website but it's marked as still active. i guess it's still used in some test&measurement equipment.
