As various kind of diagnostics information is avail-
able at pin 25 (CLIPPING, SHORTS AND OVER-
HEATING), it may be necessary to operate some
distinctions on order to treat each event sepa-
rately. This could be achieved by taking into ac-
count the intrinsically different timing of the diag-
nostics output under each circumstance.
In fact, clipping will produce pulses normally
much shorter than those present under faulty con-
ditions. An example of circuit able to distinguish
between the two occurrences is shown by fig. 15.
STABILITY AND LAYOUT CONSIDERATIONS
If properly layouted and hooked to standard car-
radio speakers, the TDA7383 will be intrinsically
stable with no need of external compensations
