ADE7816 Reference Voltage

Here’s an interesting question.  While the ADE7816  has an internal reference voltage, ADI pretty much recommends using an external reference voltage to keep it constant over temperature. 


The dev board uses an ADR208ART reference, but the website says that part is obsolete and should be replaced by the ADR3412.   My question is if I have three ADE7816 parts in the system can I use one ADR3412 for all three 7816’s or do I need three reference supplies?
