(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

VIN+ and VIN– are the voltages at the IN+ and IN– pins, respectively.

(3)

Input voltage can exceed the voltage shown without causing damage to the device if the current at that pin is limited to 5 mA.
