AD7699 REF pin voltage

Hello,

 

I use a AD7699 and I'd like to use the 4,096V internal output REF for some purpose (pin 2). However on power up I cannot see any voltage on the REF pin; its around 30 mV and it may vary (I saw it at 1,3V once, but only once). I was expecting to see it at 4,096V at power up.

 

Is this a normal behaviour ?

Thank you.
