AD7293 BI-DAC Range Selection

Using EVAL-AD7293SDZ Eval Board to set BI-DACx input register for -1.5V, but measured BI-DACx pin for +3.5V.

Settings as AVss=-5V, Offset Range -5V-0V

According data sheet page 26, the calculated input code D=0xB33 for -1.5V output(n=12, 12-bit DAC).

Is there a BI-DACx output range selection register for negative voltage output(such as -5V-0V)?

Is there anything missing to generate -1.5V instead of +3.5V?
