The datasheet states "1 MHz conversion rate". I did not dig further to see if there are limitations.
That is, by the way, 1Msps, not 1 ksps.

The product page does provide a link to the datasheet; it's in the first sentence under the 'overview' tab and you copied part of it in reply #13 
Note:
no experience with a Due.
