TDA7263L APPLICATION SUGGESTIONThe recommended values of the components are those shown on the typical application circuit. Different
values can be used; the following table can help the designer.
(*) Closed loop gain must be higher than 26dB
BUILT-IN PROTECTION SYSTEMS
5.1 Thermal Shut-downThe presence of a thermal limiting circuit offers the following advantages:
1 an overload on the output (even if it is permanent), or an excessive ambient temperature can be easily
withstood.
2 the heatsink can have a smaller factor of safety compared with that of a conventional circuit. There is no
device damage in the case of excessive junction temperature; if for any reason the junction temperature
increases up to 145°C. the thermal shutdown simply reduces the output power and therefore the power
dissipation.
The maximum allowable power dissipation depends upon the thermal resistance junction-ambient. Figure
15 shows the dissipable power as a function of ambient temperature for different heatsink thermal resis-
tance.
5.2 Short Circuit (AC Conditions)The TDA7263L can withstand accidental short circuits across the speaker made by a wrong connection
during normal play operation.
