All voltage values are measured with respect to the ground pin. 2. Differential voltage is the non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of input and output voltage must never exceed V +0.3V. CC 4. Short-circuits can cause excessive heating. Destructive dissipation can result from short-circuits on all amplifiers. 5. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a 1.5k resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 6. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5). This is done for all couples of connected pin combinations while the other pins are floating. 7. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. 2/22 Obsolete Product(s) - Obsolete Product(s)
