ELECTRICAL CHARACTERISTICS (Tamb = 25°C; VS = 12V; RL = 8Ω; f = 1KHz; unless otherwise specified.)
TDA7268
APPLICATION HINTS:For 12V supply and 8Ω 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.
