NOTES: (1) Tests are performed on high speed automatic test equipment, at approximately 25°C junction temperature. The power dissipation of this product will
cause some parameters to shift when warmed up. See typical performance curves for over-temperature performance. (2) Limited output swing available at low supply
voltage. See Output voltage specifications. (3) Typical when all leads are soldered to a circuit board. See text for recommendations.
