MICROCIRCUIT DATA SHEET
Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Operating Rating indicate conditions for which the device is functional, but do not
guarantee specific performance limits. For guaranteed specifications and test
conditions, see the Electrical Characteristics. The guaranteed specifications apply
only for the test conditions listed. Some performance characteristics may degrade
when the device is not operated under the listed test conditions.
Note 2:
The maximum power dissipation must be derated at elevated temperatures and is
dictated by Tjmax (maximum junction temperature), ThetaJA (package junction to
ambient thermal resistance), and TA (ambient temperature). The maximum allowable
power dissipation at any temperature is Pdmax = (Tjmax - TA)/ThetaJA or the number
given in the Absolute Maximum Ratings, whichever is lower.
Note 3:
Short circuits from the output to V+ can cause excessive heating and eventual
destruction.
When considering short circuits to ground, the maximum output current
is approximately 40mA independent of the magnitude of V+.
At values of supply
voltage in excess of +15Vdc, continuous short-circuits can exceed the power
dissipation ratings and cause eventual destruction.
Destructive dissipation can
result from simultaneous shorts on all amplifiers.
Note 4:
This input current will only exist when the voltage at any of the input leads is
driven negative.
It is due to the collector-base junction of the input PNP
transistors becoming forward biased and thereby acting as input diode clamps. In
addition to this diode action, there is also lateral NPN parasitic transistor action
on the IC chip.
This transistor action can cause the output voltages of the op amps
to go to the V+ voltage level (or to ground for a large overdrive) for the time
duration that an input is driven negative.
This is not destructive and normal output
states will re-establish when the input voltage, which was negative, again returns to
a value greater than -0.3Vdc (at 25 C).
Note 5:
Human body model, 1.5K Ohms in series with 100pF.
