Notes: 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.

1. The input and output negative voltage ratings may be exceeded if the input and output clamp

current ratings are observed.

2. This value is limited to 4.6 V maximum.

3. The maximum package power dissipation is calculated using a junction temperature of 150°C

and a board trace length of 750 mils.
