Hi Emman.A

Please post your answer as soon as you have one.

Thank you

Hi Ignacio,

Sorry for getting back late. We have an analog isolator circuit which you may want to consider. It is implemented by using AD7400A, an Isolated Sigma-Delta Modulator.  Here is the link of the reference circuit: 

http://www.analog.com/media/en/reference-design-documentation/reference-designs/CN0185.pdf.

If this solution is not applicable on your circuit then I suggest to post your questions in Interface and  Isolation Community. They may have different approach and solution on this kind of circuit design.

I hope this helps.

Best regards,
Emman
