ADL5372
EVALUATION BOARD
Populated RoHS-compliant evaluation boards are available for
evaluation of the ADL5372. The ADL5372 package has an
exposed paddle on the underside. This exposed paddle must
be soldered to the board (see the Power Supply and Grounding
section). The evaluation board is designed without any
components on the underside so heat can be applied to the
underside for easy removal and replacement of the ADL5372.
