Handling of NC pins: It is recommended to connect all NC pins on a defined potential. E.g. pin 7 and pin 12
could be connected to OUT potential, while pin 5 and 6 could be connected to OUT or DEN.
EMC filter cap between Vbb and GND: It is recommended to place the filter cap as close as possible to the
device to minimize the inductance of the loop.
The resistors connecting µC and IN-pin as well as µC and DEN-pin are recommended to protect the µC inputs
against fast electrical transients.
Ground shift: It is recommended to avoid a ground shift between µC ground and device pin GND of more than
0.3V during normal operation.
