Notes:
Stresses beyond those listed under âabsolute maximum ratingsâ 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 ârecommended operating
conditionsâ 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.
