Is it possible to use an AD620 connected to an AD210 to measure high-side current through a sampling resistor? With the REF line on the AD620 and the Icom line on the AD210 connected to the bottom of the resistor (and the top of the resistor is connected to 2KV). The REF/Icom voltage measured with respect to ground would be very close to 2KV.
If I were to do that what ground referenced voltage would I measure at +VISS on the AD210? Would it be 2KV - Rsense*Iload + 15V? That is, assuming I didn't let the smoke out. ;-)
Are there any common mode limits I need to be careful to watch out for?
