I am using AD5752R in 0-10V operation. But its getting configured only to 0-5V range. Wat may be the reason?
Although the part has not been configured to the desired output range yet, does it work with the default +5V range? Can you configure the rest of the registers and get the expected output voltages when you write a data to it? Is /LDAC tied permanently low, or is it held high during the write cycle and brought low to update the DAC registers?
You could be facing a timing issue, so a scop plot of the /SYNC, SCLK, /LDAC, SDIN lines would be useful to assure that the interface timings match with the datasheet.
