(1)

Stresses beyond those listed under Absolute Maximum Rating 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 Condition. 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.
