Is power down cirsuits in AD5689R?

Hello AD5689R include Power donw cicruit with normal and  three-state output mode. my question is.

This mechanism can be used as a switch, for connect and disconnect DAC to amplifier?

For example DAC is in tree-state,

I set DAC on 2,5V over LDAC pin (time=0),

set powerdown register to normal operation

on output to 10k Load  is direct on +2,5V or +5,0 for Gain2 (time=+4,5us ?)

In other words, does it behave the same as when I connect an analog switch to the output?

What will happen for the time of 4.5us?
