I am using the AD628ARMZ in my design.
From time to time it happens that the device fails to operate according its specifications and becomes defective:
- Output voltage got a 1V drift at its output (in one card)
- Output voltage failed to zero (in another card).
Replacing the parts solved the problem.
Pls see the schematics below. Can you see a reason for this behavior?
Please note that the Vin to the device is provided before the +Vs -Vs of the card/device itself. Can it be a problem?
