Usually that stuff scales with the master clock frequency.

There are a couple of shorted-input graphs on page 11.  They go down to 1 Hz. 
 Figure 15 on the next page goes down to 0.2 Hz.

For EFC type uses, I'd expect the drift over temperature to be the major problem, or maybe the temperature drift of the reference voltage.

I suppose you could put them in an oven.

These are my opinions, not necessarily my employer's.  I hate spam.
