Routing AD7147

Question

Dear ADI Zone,

here my new tentative routing. What do you think about it? I am using two AD7147 even if I know that you discourage it. Apart from that, do you think it is fine?

what about the two AD7147 instead? can I do something else to avoid possible noise issues while keeping the fact of having two in the same pcb? 
 
 Thank you very much in advance, 
 
 best regards, 
 
 Gianluca

Hi Gianluca, This routing is much improved, the CIN traces do not cross over each other or the senor pads. It looks good. 
 The two AD7147 devices and their respective sensors should be separated from each other as much as possible. 
 If you do experience noise issues (which will be less the further the devices are separated from each other) then you may need to sequence the two devices so that only one of them is active at any one time. 
 Regards, 
 Maurice.
