Hi all,

 

The DAC INPUT DATAPATHS @ AD9102 have the following two functions.

DAC digital gain multiplier, and a DAC digital offset summer.

 

Other DDS series perhaps does not have these functions, only to the best of my knowledge,but only in my experience.

We can not understand these functions.


The 14-bit samples are input to the DAC @ AD9102, but these function are 12-bit value.

The 12-bit value shift to MSB or LSB? Then, results ?

 

Please advise how to use these functions,and to calculate the datapath value.

 

Best regards,

sss
