This DAC has differential outputs. The full scale output is specified as 3.2Vpp. The bipolar zero voltage is specified as 1.4V. Questions: Is there a common mode voltage on the high and low outputs? Does the high output swing above and below the low output, or is it unipolar? Asking another way, what are the absolute voltages (referenced to ground) of the high and low output at zero scale and at full scale?
We are looking into this for you.

The analog output should be centered around the bipolar zero, so yes there should be a common mode voltage on both high and low outputs of roughly 1.4V, with absolute voltages ranging from 2.2 to 0.6V roughly.
Thank you, Patrick. That clears it up for me.
