APPLICATION HINTS:

For 12V supply and 8

Ω

speaker application, its

maximum power dissipation is about 2W.

Assumming that max ambient temperature is

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 C

svr

current.
