We use these as D to A converters for vector graphics down to DC.
EBAY item # 160284015210
Ordered (BiN). For $23 it's worth it just as a test, out of my
pocket.
No problems so far, and we actually SEE any errors.
A very rare "pop" if you have too many processes running on the
control CPU, but thats it.
A pop wouldn't bother me. I can still make the measurements.
We modify them for DC coupling, bypass the caps and add a op-amp for
offset.
Don't need DC coupling, but that's good to know. If this works
maybe I'll buy a pile of 'em. ;-)

I have not seen any HF hash on a 100 mhz scope.
That was only one of the problems, but a biggie.
Thanks for the pointer. I'll let you know how it goes.
