DAC update rate

I plan to use AD5672, but the update rate is not described in parametric search and AD5672 data sheet.

 

DAC Parametric Search with update rate

http://www.analog.com/en/parametricsearch/10933#/p4910=Precision%20DAC&d=sel|0|4527|s8|4910|7|165|4458|3899|4737|4129|3970|s3|s5


How do I think the update rate?
(compare the slew rate and input shift register time (t1 x 24bit) and choose the longer time?)

Would you tell me the AD5672 update rate?

    Hi,

    1) Please use the OUTPUT VOLTAGE SETTLING TIME spec in Table 4 as the Tsettle for AD5672R

    2) Settling time starts from the /SYNC rising edge. As for the difference between Figure 41 and Figure 51, I'll get back to you on that. 

    Cheers,

    Ivan
