Reference of AD5542A in bipolar mode

Dear AD engineers,

Could I ask if +5V/-5V is supported for AD5542A in bipolar mode? It is specified in datasheet everywhere that a 2.5V reference should be used, such as in page 8: Pin REF Connect this pin to an external 2.5 V reference.

Thanks a lot.

Regards,

Richie
