Regarding the Vrefout output current capability of the AD5643R

Hi knj 

Unfortunately, we do not have this data. The reference should be designed to have enough current capacity to drive the internal DAC cores but if required to drive external loads, a buffer is needed as suggested in the datasheet. 

Best regards,

Ian
