PCF 8591 analog input capacitance and voltage source interface resistance

Question asked by ikki horiuchi on Mar 9, 2017

Hello everyone.
I am reading the data sheet of PCF 8591.
So I have a question.
There is no provision of [voltage source interface resistance], [analog input capacitance] in the data sheet. Is it actually unnecessary?

By the way, there is description in other data.

e.g LPC1769 datasheet is write in 62page analog input capacitance and voltage source interface resistance.
