Hi,

 

I want to replace an old isolation amplifier by an AD 215 with the same caracteristics. I try to realize the unity gain input circuit in the data sheep. But I have a problem with the isolated +/-15V dc power supply.

I apply +/-15V on +/-15V dc Power and I receive +/-5V on my isolation power supply.

 

Out low and PWR RTN are linked that why I don't understand the problem of the isolated power supply.

 

Can u help me please?

 

Thank for your help.

 

C.L
