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.
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
