Question about AD5317R

Hi there,

 

I have a question about AD5317R.

http://www.analog.com/media/en/technical-documentation/data-sheets/AD5317R.pdf

My question is about the link between Vdd voltage and Internal Reference.

In case of the following condition,

 Vdd =3.3V, Vref =Internal(2.5V ), AMPGain=2,

Does the output voltage span is 0 to 5V(2*2.5V)?  or 0 to 3.3V(due to the Vdd voltage)?

Please give me advice where the amplifier power source comes from either Vref or Vdd.

 

Best regards,

Tarzan
