Have got this DAC circuit:

Are my calculations of Vout, Vout_max and step size correct?

Is there are any other important parameters that can be calculated?

 

Can't think of any you might need offhand, but I suggest adding some decoupling capacitors to all of the power supplies.

 

What does the data sheet have to say?

Is the data sheet happy tying Iout- to ground?

It's been a long time since I've worked with one of these DACs.
