Layout and grounding
For a high system performance level certain grounding techniques are essential.
The input reference grounds have to be tied with their respective source grounds and
must have separate tracks from the power ground tracks; this will prevent the large
(output) signal currents from interfering with the small AC input signals.
The small-signal ground tracks should be physically located as far as possible from
the power ground tracks. Supply and output tracks should be as wide as possible for
delivering maximum output power.
