Exposed pad on ADA4084-2

What's the consequence of leaving the exposed pad unconnected on the ADA4084-2? The datasheet says it must be connected.  Will the result be poor thermal performance or are there other potential issues


  The part is SOI, so it's mostly a thermal consideration, but there are some parasitic capacitances

that would say connecting to Vee is the best.  Ground is second best.
