Is it possible to interconnect the outputs of 4 ADG406 if only 1 switch of the 4 ADG406 is switched?
Yes, you can. But, bear in mind that the parameters of this new configuration will not be the same as in the datasheet since that is for a single ADG406.
In this case, you will have added capacitance…
thank you for the informations.Then I will definitely seal it with the respective enable pins and connect the outputs (parallel).
