Normally the clip detector signalling produces a
low level at pin 10 thatis shorter than that present
under faulty conditions; based on this assumption

tion is representedin theschematicof fig.26.

PCB-LAYOUT GROUNDING (general rules)
The device has 2 distinct ground leads, P-GND
(POWER
GROUND)
and
GROUND) which are practically disconnected
from each other at chip level. Proper operationre-
quires that P-GND and S-GND leads be con-
nected together on the PCB-layout by means of
reasonablylow-resistance tracks.
As for the PCB-ground configuration, a star-like
arrangement whose center is represented by the
supply-filtering electrolytic capacitor ground is
highly advisable. In such context, at least 2 sepa-
rate paths have to be provided, one for P-GND
and one for S-GND. The correct ground assign-
S-GND
(SIGNAL
mentsare as follows:
STANDBY CAPACITOR, pin 7 (or any other
standbydriving networks): on S-GND
SVR CAPACITOR (pin 6): on S-GND and to be
placed asclose as possible to the device.
INPUT SIGNAL GROUND (from active/passive
signal processorstages):on S-GND.
SUPPLY FILTERING CAPACITORS (pins 3,13):
on P-GND. The (-) terminal of the electrolytic ca-
pacitor has to be directly tied to the battery(-) line
and this should represent the starting point for all
the ground paths.
