external reference impedance

Question

I am planning to use the LPCOMP in conjunction with an external reference. I would like to just use a voltage divider to create the external reference. 
 Are there any impedance requirements for the external reference?

Hi Lucas 
 Having high impedance instead of low impedance voltage source for the LPCOMP external reference will not have any noticable effect on the output of the LPCOMP
