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-circuit from the output to V
CC
+
can cause excessive heating and eventual destruction. The maximum output current
is approximately 20mA, independent of the magnitude of V
CC
+
.
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 diodes clamps. In addition to this
diode action, there is also 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 duration than an input is driven
negative. This is not destructive and normal output will set up again for input voltage higher than -0.3V.
5. R

are typical values.
6. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a 1.5kΩ resistor
between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
7. 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 < 5Ω). This is done for all couples of connected pin combinations
while the other pins are floating.
8. 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.
