TDA1565TH
Heatsink design
There are two parameters that determine the size of the
heatsink. The first is the rating of the virtual junction
temperature and the second is the ambient temperature at
which the amplifier must still deliver its full power in the
BTL mode.
Example:
With a conventional BTL amplifier, the maximum power
dissipation for a typical signal, such as music (at each
amplifier)willbeapproximatelytwotimes15 W.Atavirtual
junction temperature of 150
°
C and a maximum ambient
temperature of 65
°
C, R

= 1.8 K/W and

= 0.2 K/W. For a conventional BTL amplifier the
thermal resistance of the heatsink should be:
Compared to a conventional BTL amplifier, the
TDA1565TH has a higher efficiency. The thermal
resistance of the heatsink should be:
