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.
