Note 1: Dissipation wattage values are based on still air with no heatsink. Actual maximum power dissipation is a function of heat
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 in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

extraction technique and may be substantially higher. Package thermal resistances were obtained using the method
described in JEDEC specification JESD51-7, using a four-layer board. For detailed information on package thermal consid-
erations, refer to www.maximintegrated.com/thermal-tutorial.
