(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

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 operational amplifer

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

−0.36V (at 25°C).

(3)

Short circuits from the output 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 +15V,

continuous short circuits can exceed the power dissipation ratings and cause eventual destruction.

(4)

The maximum power dissipation is a function of TJ(MAX),

θJA , and TA. The maximum allowable power dissipation at any ambient

temperature is PD = (TJ(MAX) - TA)/

θJA. All numbers apply for packages soldered directly onto a PC board.
