ADA4528-1 as an ADC Reference Buffer

Can the ADA4528-1 handle large capacitive loads ( > 4.7µF) and drive the reference of a high precision sigma-delta like the AD7173-8?

I do not want to add source resistance between the output of the amp and the input of the reference of the ADC.  Will the 200kHz noise from the chopping frequency affect the performance of the converter without a filter?  Perhaps a snubber network is advised if the ADA4528 is to be used in this application?
