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 an 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 an 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 - 36 V)/400 μA).

6. Short-circuits can cause an 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.

9. 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.
