Absolute Maximum Ratings

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage

parameters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are

measured under board mounted and still air condition.

Note1:

In any case, power dissipation should not exceed

PD.

Note2:

Voltages above the absolute maximum ratings may damage the chip.

Recommended Operating Conditions

For proper operation the device should be used within the recommended conditions. The

VS offset rating is tested

with all supplies biased at a 15V differential.
