ADL5370
EVALUATION BOARD
Populated RoHS-compliant evaluation boards are available for
evaluation of the ADL5370. The ADL5370 package has an
exposed paddle on the underside. This exposed paddle must
be soldered to the board (see the Power Supply and Grounding
discussion in the Basic Connections 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 ADL5370.
