Remark:
Switching inductive loads, the output voltage can rise beyond the maximum
supply voltage of 28 V. At high supply voltage it is recommended to use (Schottky)
diodes to the supply voltage and ground.

Layout and grounding
To obtain a high-level system performance, 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.
