Multiple AD7147 firing measurement sequentially

Hi there,

 

I have a board with multiple AD7147 chips. Is there a way to synchronize them so that they fire measurements sequentially (one after another).

 

Right now, the interrupt pin is set to be conversion interrupt. I'm thinking if I can suspend all but one chip at any given moment I might be able to achieve the synchronization. But I don't know how to do it.

 

I want to do this because I found interference between two chips, if I touch on two sensors from different chips samultaneously.

 

Any help will be appreciated.

 

Thank you.
