"2" The tabs on the TBA800 can be used to conduct away the heat generated in the integrated in the integrated circuit so that the junction temperature does not exceed the permissible maximum 150C). This may be done by connecting tabs to an external heat sink, or by soldering them to a suitable copper area of the printed circuit board. External heat sink or printed circuit copper area must be connected to electrical ground. j- (Ta= +) Power Dissipation Pr (W) Thermal Resistance @j-a@ (C/W) (Ta =70C ) HITACHI 169TBA80O POWER RATING CHARACTERISTICS OUTPUT POWER VS.
