Note 1: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the de-

vice beyond its rated operating conditions.

Note 3: More accurately, it is excessive current flow, with resulting excess heating, that limits the voltages on all pins. When any pin is pulled a diode drop below

and unpredictable when any parasitic diode or transistor is conducting.

Note 7: All limits are guaranteed at room temperature (standard type face) or at operating temperature extremes (bold type face).

Note 8: Slew rate is measured with op amp in a voltage follower configuration. For rising slew rate, the input voltage is driven from 5V to 25V, and the output voltage
