Hi,
Which pin is internally connected to AD5761/AD5721 LFCSP EXPOSED PAD? Can I connect the exposed pin directly to AGND/DGND pins in BI-POLAR output configuration or just in UNI-POLAR output?
Best regards,

Hi,
You can leave the exposed pad floating or tie it to the lowest potential which is VSS pin.

Hi Ivan,
I'm glad I found this information.
But this should probably be stated in the datasheet as well. Currently there is only the note it can be left floating, but nowhere any mentioning on what is the internal connection (even though VSS is the expected potential you never can be sure).

Hello armin,
Alternatively, you can connect the exposed pad to a floating pad with vias on board for heat dissipation and better pcb mounting. We will take note and update this information on future revisions of the datasheet.
Best regards,
Ian
