Layout Considerations
The MAX9981 evaluation board can be a guide for your
board layout. Pay close attention to thermal design and
close placement of parts to the IC. The MAX9981 pack-
age exposed paddle (EP), conducts heat from the part
and provides a low-impedance electrical connection.
The EP must be attached to the PC board ground plane
with a low thermal and electrical impedance contact.
Ideally, this can be achieved by soldering the backside
package contact directly to a top metal ground plane on
the PC board. Alternatively, the EP can be connected to
a ground plane using an array of plated vias directly
below the EP.
Depending on the ground plane spacing, large sur-
face-mount pads in the IF path may need to have the
ground plane relieved under them to reduce shunt
capacitance.
