ALTERNATE PCB LAND PATTERNS
The ADMP421’s standard PCB land pattern has a solid ring
around the edge of the footprint, which may make routing the
microphone signals more difficult in some board designs. This
ring is used to improve the RF immunity performance of the
ADMP421, but it is not necessary to have this full ring
connected for electrical functionality. If a design can tolerate
reduced RF immunity then this ring can either be broken or
removed completely from the PCB footprint. Figure 10 shows
an example land pattern with no enclosing ring around the edge
of the part, and Figure 11 shows an example pattern with the
ring broken on two sides so that the inner pads can be more
easily routed on the PCB.

Note that in both of these patterns, the solid ring around the
sound port is still present; this ring is needed to ground the
microphone and for acoustic performance. The pad on the
package connected to this ring is ground and still needs a solid
electrical connection to the PCB ground. If a pattern like one of
these two examples is used on a PCB, take care that the
unconnected ring on the bottom of the ADMP421 is not placed
directly over any exposed copper. This ring on the microphone
is still at ground and any PCB traces routed underneath it need
to be properly masked to avoid short circuits.
