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.

ELECTRICAL CHARACTERISTICS

ABSOLUTE MAXIMUM RATINGS

Note 1: LX has internal clap diodes to PGND and IN1. Applications that forward bias these diodes should take care not to exceed

the IC’s package-dissipation limits.

Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-lay-

er board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
