ADA4637-1 and OP37 pin compatibility in SOIC

Question Are ADA4637-1 and OP37GSZ in SOIC package pin compatible? Answer ADA4637-1 and OP37GSZ, are not pin compatible. But if you can externally short pin 5 and 8, then they become pin compatible.

OP37: Reversal of supply voltage

Question I have had a query from a customer they have wired an OP37 incorrectly. Instead of +15V and 0V they have applied -6V on the V+ pin and +5V on the V- pin, the parts were then powered up and the error realized. The problem was corrected and the parts still seem to work. The question is what is likely to have been damaged? Answer The OP37 contains no on-chip circuitry for protection against reversal of supply voltage. If the OP37 has been exposed to a condition where V+ (pin7) is more negative than V- (pin4) the OP37 has been permanently damaged. All parts should replaced and discarded. Damage due to supply reversal may occur as a catastrophic failure or may be cumulative in nature and manifest as an early life failure. The fact that the part “seem to work” should not be taken to mean that the parts have not been damaged. Typical failure mechanisms included metal migration of connecting tracks due to high currents, parasitic diodes and SCR mechanisms causing damage to transistor base (partial punch through effect) and excess localized heating upsetting transistor matching.
