Thermal Grounding and Evaluation Board Layout

The package for the ADL5375 features an exposed paddle on

the underside that should be well soldered to a low thermal

and electrical impedance ground plane. This paddle is typically

soldered to an exposed opening in the solder mask on the

evaluation board. Figure 78 illustrates the dimensions used in

the layout of the ADL5375 footprint on the ADL5375 Evaluation

Board (1 mil. = 0.0254 mm).

Notice the use of nine via holes on the exposed paddle. These

ground vias should be connected to all other ground layers on

the evaluation board to maximize heat dissipation from the

device package.

Under these conditions, the thermal impedance of the ADL5375

was measured to be approximately 30°C/W in still air.
