AD5762R reference range vs. analog power supply range

Dear Colleagues,

Is the external reference voltage applied to REFA and REFB pins of AD5762R DAC amplified x2 inside the chip before applying to the internal R-2R DACs?

To make it more clear: let's assume that AD5762 has +-15V analog power supply and +7.5V reference.

Will it work with limited output range +-13.6V?

Or will not because a reference amplifier inside will saturate?

Thank you!
