AD4667R out of spec

for me it's the first time using analog devices products. I've asked and received a sample of the AD4667R DAC

Yesterday i've started to write the code for it. After a while i realize that the output that the dac is giving is 500mV over the setting. For example, with all zeros loaded into the dac i read about 500mV on the output. So i've measured Vref out and i measure about 3V instead of 2.5V that the datasheet says. 
Why is it so out of spec?
