Driver Output
Solid GND plane with vias
close to decoupling points
for low impedance return
path
Several Via connection
between top and bottom
ground layers for EMI and
Thermal performance
Star routing for better
thermal performance
High Frequency
Decupling Capacitor
placed as close as
possible to the device
Refer to
for a detailed
description of the
filter design
SLOA119
Wide open areas for
thermal flow
Bulk Capacitor for
good audio
decoupling close to
PVDD source
Wide space
between driver
output traces
