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?
Yes you can use an external switch to get a higher slew rate, however you should watch out for transient currents due to load capacitance and high dV/dt.
