1.
All voltage values, except differential voltage, are with respect to the zero reference level (ground) of the supply voltages where the zero reference level is the midpoint between V
CC
+
and V
CC
-
.
2.
The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.
3.
Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
4.
Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all amplifiers.
5.
Rth are typical values.
6.
The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not exceeded.
7.
Human body model: 100 pF discharged through a 1.5 k
Ω resistor between two pins of the device, done for all couples of pin combinations with other pins floating.
8.
Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5
Ω), done for all couples of pin combinations with other pins floating.
9.
Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground.
