Note 1: LX has internal clamp diodes to PGND/AGND and SUP. Applications that forward bias these diodes should take care not to

exceed the IC’s package power-dissipation limits.

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.

Note that a “+”, “#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different

suffix character, but the drawing pertains to the package regardless of RoHS status.

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/
