1. Either or both input voltages must not exceed the magnitude of V
CC
+
or V
CC
-
. All voltage values, except differential voltages
are with respect to 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 V
CC
can cause excessive heating if V
CC
> 15 V. The maximum output current is
approximately 40 mA independent of the magnitude of V
CC
. 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 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 V
CC
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. Destructive dissipation can result from simultaneous short-circuits on all
amplifiers. These are typical values given for a single layer board (except for TSSOP, a two-layer board).
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
external series resistor (internal resistor < 5 Ω), into pin-to-pin of device.
9. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to
ground.
