Table 1.
1. Either or both input voltages must not exceed the magnitude of V
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
3. Short-circuits from the output to V
4. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base
5. The junction base/substrate of the input PNP transistor polarized in reverse must be protected by a resistor in series with
6. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all
7. Human body model, 100 pF discharged through a 1.5 kΩ resistor into pin of device.
8. Machine model ESD: a 200 pF capacitor is charged to the specified voltage, then discharged directly into the IC with no
9. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to
