ADR444 Incorrect Output Voltage

I am trying to use the ADR444 as a 4.096V reference for the ADAS3023, using the AD8031 as a buffer, as suggested on the ADAS3023 data sheet.  The ADR444 is giving about 4.3V, which is dropping to 4.2V after the AD8031.  Both of these are operating off 5V input.

 

I don't know that this will be a major issue, but I wonder if it's possible I'm missing something.
