Package Thermal Characteristics (Note 1)

Electrical Characteristics

Note 1: 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 considerations, refer to

www.maximintegrated.com/thermal-tutorial.

Thermal resistance can be lowered with improved board design.

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.
