1. All voltage values, except differential voltage are with respect to network ground terminal.

2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.

3. Short-circuits from the output to VCC can cause excessive heating if (Vcc +) > 15 V. The maximum output current is approximately 40 mA,

independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuits on all amplifiers.

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 junction of the input

PNP transistor becoming forward-biased and thereby acting as an input diode clamp. In addition to this diode action, there is NPN parasitic

action on the IC chip. This transistor action can cause the output voltages of the op amps to go to the VCC voltage level (or to ground for a

large overdrive) for the time during which an input is driven negative. This is not destructive and normal output is restored for input voltages

above -0.3 V.

5. The junction base/substrate of the input PNP transistor polarized in reverse must be protected by a resistor in series with the inputs to limit

the input current to 400 µA max (R = (Vin - 32 V)/400 µA).

6. Short-circuits can cause excessive heating and destructive dissipation. Values are typical.

7. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of

the device. This is done for all couples of connected pin combinations while the other pins are floating.

8. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no

external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating.
