APPLICATION HINTS:
For 12V supply and 8
speaker application, its
maximum power dissipation is about 2W.
Assumming that max ambient temperature is
70
°C. Required thermal resistance of the device
and heat dissipating means must be equal to (150
- 70)/2 = 40
°C/W.
Junction to pin thermal resistance of the package
is about 15
°C/W.
That means external heat sink of about 25
°C/W is
required. Stand-By switches must be able to dis-
charge Csvr current.
