What is the AD5673R Channel Output Voltage?

Category: Datasheet/Specs
Product Number: AD5673R

I can't believe I have to ask this here, but I can't seem to make sense of the datasheet. 

On page 23 under "Output Amplifiers", the datasheet says that the outputs are rail to rail, or 0 to VDD. My VDD is 3.3V. How do I configure this device to produce 0-3.3V on the analog outputs? Is it even possible?

Can this device be used with an external reference? In table 1 on the first page, it looks like this device (16 channel, I2C) is hardwired to use an internal reference. However, elsewhere the internal reference is described as "default." On page 28, under Internal Reference Setup, DB0 is used to disable the internal reference.  Can the internal reference be disabled on this device so that VREF (pin 21) can be used as an input for an external reference?

Thanks

Doug
