Philips Semiconductors Product specification 3 W mono BTL audio amplifier with DC volume control TDA7056AT TEST AND APPLICATION INFORMATION Thermal behaviour: Test conditions The measured thermal resistance of the IC package is highly dependent on the configuration and size of the application board. Data may not be comparable between different semiconductors manufacturers because the application boards and test methods are not (yet) standardized.
