(1)

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

only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating

Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

Use the following equation to make sure that the maximum value of IOUT in a given application is less than 400 µA:

where:

● IOUT,MAX is the estimated maximum value of IOUT

● VSENSE,MAX is the maximum possible value of the differential input voltage in the application

● VIN+,MAX is the maximum possible value of VIN+ in the application

● V+MAX is the maximum possible value of V+ in the application

● RLOAD is the value of the load resistor in kΩ
