I'm presuming the 384MHz was a typo for 384kHz.

$20 I presume is the BoM cost of the ADC and is probably OK ... $100 of the list price?
A question, though, has to be whether we really need it. 384kHz sampling rate is good, though the data rate doesn't really need to be that high; but 64bit is probably totally pointless. I think that's a resolution way beyond what physics will allow. It's a huge amount of data and for what purpose?
