Hi Joe,

ADC input impedance between 20kOhm and 40 kOhm
Input capacitance 1 pF
There is no Fifo. Using one of the continuous modes requires servicing
through interrupts before another conversion is done otherwise loss of
data. 
The ADC is not modeled on the 80C552, it is a new development.

The ADC on all 3 above mentioned devices is the same though.
Hope this helps

Robert
