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 https://www.analog.com/en/technical-
