The data sheet on pages 6 and 7 shows different values for the noise density: 250 nV/√Hz@1KHZ (on page 7) and 90 nV/√Hz (on page 6) What is the difference between these two specs and which is the actual number?

Matt,
One specification (the one on page 6) is for the DAC itself assuming a very low noise external reference. The specification on page 7 is for the internal reference.
