I am using a AD627 for my 4-20ma receiver, now I want to add an Analog isolation amplifier, my circuit has a 5VDC simple power suply, wich IC do you will use for this? thanks

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
