Hi friends,


I am using AD768ARZ (DAC) in my project.


i am generating Bipolar  ±2.5 V signal directly from DAC output (according to figure 25 reference in datasheet) .


i am drawing 2.5mA current for offset voltage for bipolar signal and 5mA of current for IREFIN .


I am also sharing 16 bit digital data between same DAC chips with seperate clock signal . Clock signal acts as control signal to select the particular DAC.i have enclosed the image of my design.


Please let me know ,Is thre any issuse with above configuration.



I am new to analog design,Please give me any tips and guidelines for AD768ARZ.



Thanks and Regards
