Unable to operate AD5752R in 0-10V range

I am using AD5752R in 0-10V operation. But its getting configured only to 0-5V range. Wat may be the reason?

    Hi,

    It is working fine in default +5V range. I am able to configure the rest of the registers and am getting the expected voltage corresponding to the data written to it. I am keeping /LDAC high during the write cycle and brought to low in order to update the DAC registers.

                    In one of the boards its working perfectly in +10V and in another board I am facing this problem. I also think that its a timing issue.I will plot the signals and will update you the situation.
