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.
