AD5316R with external reference

I'd like to use the AD5316R with an external reference but there's no information on the current draw of the VREF pin when in external mode.

Since it starts in internal mode, I can't connect an external reference to it directly, and I have to use either a resistor Pull-up/pull-down or a serial resistor to an accurate reference device (preferred).

If the current draw is large, I have to make this resistor small and account for it.

What is your recommended scheme in this case?
