APPLICATION HINTS: For 14.5V supply and 8Ω speaker application, its maximum power dissipation is about 1.8W. Assumming that max ambient temperature is 70°C, the required thermal resistance of the de- vice mounted on the PCB with a dissipating area must be equal to: (150 - 70)/1.8 = 44.4°C/W. Junction to pin thermal resistance of the package is about 15°C/W. That means external heat sink of about 30°C/W is required. Cu ground plane of PCB can be used as heat dis- sipating means.
