Electrical Characteristics
LM3622-XX
Symbol
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2: V
Note 3: Rating is for the human body model, a 100 pF capacitor discharged through a 1.5kΩ resistor into each pin.
Note 4: The maximum power dissipation must be de-rated at elevated temperatures and is limited by T
ambient thermal resistance) and T
listed in the Absolute Maximum Ratings.
Note 5: Limits reflect initial accuracy.
