Dear AD team,

We have used AD8221ARMZ  in one of product, which is proven and going in volumes.

Recently we have procured some 1000 No's IC'S(date code 2020+) and after assembly when we took for testing, moment we power on the card these AD8221 IC's are going bad, showing short between +VS with +IN pin or -VS with +IN, 

Kindly do not doubt on Board design, assembly, since this product is proven and other batch of AD8221 IC's are working fine in the same board

Kindly update why this is happening, matter is serious
