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
