EVAl-AD5679RSDZ

Question

Dear community,
I am working with the board EVAl-AD5679RSDZ, it works well, but I have a question about the external voltage reference for the DAC, I did not find a value for the VREF in the user guide or the data sheet.
How big can be the value of the external voltage reference for this DAC?
Best Regards,
Iordan Pentchev.

Hi Iordan, 
 The reference input range for the AD5679R is 1 to Vdd (Gain=1) and 1 to Vdd/2 (Gain=2). The absolute max is VDD+0.3V. These can be found on Table 2. and Table 7 of the ds.
