There appears to be a cut and paste error in the AD5370 (16 bit) vs AD5371 (14 bit) datasheets. On page 18 on both datasheets, top of the right hand column it mentions that the default code for X1A and X1B is 5461 for both the 14 bit (AD5371) and the 16 bit (AD5370) Is this correct? I'm guessing should be 21844 (4x5461) for the 16 bit version. Can someone confirm this? If I use the value from the datasheet the power up output voltage using a 3V reference is -3V which doesn't sound right and will not work in my design.
The default code for the AD5370 X1A and X1B registers should be should be 21844. Upon power up, the OFFSET_CODE is at 0x2000 or 8192.
Thanks you for pointing this typo, we will have the data…
