So I am planning to use an AD620 instrumentation amplifier in my circuit. The gain formula is G = 1+(49.4KOhm/Rg), Rg being the deciding resistance value. By that logic if a 100K preset or Pot is set to zero, Gain attempted is (∞ + 1), which besides being impossible is also way above the 10000 max gain mentioned for this Instrumentation Amplifier. Would such a situation be safe for the amplifier or would it cook it up? What exactly happens in such situations?
