Solder the exposed pad on the underside of the ADL5724 to a low thermal and electrical impedance ground plane. This pad is

typically soldered to an exposed opening in the solder mask on

the evaluation board. Connect the ground vias to all other
(d 6
ground layers on the evaluation board to maximize heat
URE 5 IG
dissipation from the device package.
