further connections to other components
or ground paths are not allowed
only this path may be connected
to general ground of PCB
For optimum performance of the TDA4853; TDA4854 the ground paths must be routed as shown.
Only one connection to other grounds on the PCB is allowed.
Note: The tracks for HDRV and BDRV should be kept separate.
pin 25 should be the 'star point'
for all small signal components
no external ground tracks
