Preliminary Technical Data
EVALUATION BOARD
Populated RoHS-compliant evaluation boards are available for
evaluation of both versions of the ADL5375. The ADL5375
package has an exposed paddle on the underside. This exposed
paddle must be soldered to the board for good thermal and
electrical grounding. The evaluation board is designed without
any components on the underside, so heat can be applied to the

should it become necessary.
Both versions of the ADL5375 share the same evaluation board
and schematic. To differentiate the boards from each other, the
silkscreen on the underside of the board has a table that is marked
to indicate which version (-05 or -15) is populated on the board.
