DAC081C081: ho w estimate the voltage difference between Vref and VA rail

Part Number: DAC081C081


Hi team,

    DAC081C081CISD ( 6 pins) is designed with 3.3V at VA pin, where VA pin is used as reference voltage for internal DAC as well. My question is how I can estimate the max. Vout voltage level? Guessed the DAC Vout should be less than 3.3V in real case. So how do I calculate the difference voltage from parameters on data sheet?

   Customer measures VA is 3.277V, however Vout = 3.153V only. Thus 

1. How do I calculate the voltage difference?

2. Any way to make Vout higher than 3.2V?

Thanks.
