Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.
Note 2: Derate at 150˚C/W for operation at ambient temperatures above 75˚C.
Note 3: For supply voltages less than
±
22V, the absolute maximum input voltage is equal to the supply voltage.
Note 4: These specifications apply for V
