What is the input impedance of port P0_30/AIN6 when operating as an ADC input

What is the input impedance or input current of port P0_30/AIN6 when operating as an ADC input?  Nominal or typical figures would be OK, but maximum and minimum figures would be even better.

The reason I am asking is because I am using this port to monitor an analog voltage that is fed via a potential divider, so I would like to understand the highest resistor values I can use in the potential divider without causing significant errors in the ADC measurement.
