Driving reference input on AD8495

Data sheet indicates use of low-impedance source to offset the AD8495 output. Question is how low is low?

Reference input is specified as having typical 60K input but also 25uA typical input.

I would like to drive this with a resistive divider of 3900R/97.6R from 4096mV giving 100mV offset.

Can I safely assume the current sinks to the negative supply terminal (I am using single-ended configuration)?
