Can the AD5735 be used in single supply configuration?

I received this inquiry from a customer:

In our design the AD5735 will only be used in a unipolar output mode, therefore I would like to know if the AD5735 AVss pin can be tied to gnd instead of a negative supply. I would prefer not to have to add a negative supply to the design if it is not necessary.

The datasheet list the range for as -10.8 <= AVss <= -26.4. 

  • Is there any way to make the AD5735 work correctly without a negative supply? 
  • If not, how much current should the negative supply be capable of sourcing/sinking? 
  • Any suggestions for generating the required negative supply.

  • Hi Lionel,

    Both the AD5755 and AD5735 have the -Vsense Buffer, no issues here but my response earlier covers both these products. A bipolar supply is required at all times.

    The AD5755-1 replaces it with CHART for HART functionality.

    The AD5757 and AD5737 are current output only DAC's

    Regards,

    David
