Philips Semiconductors Product specification
Low voltage mono/stereo power amplifier TDA7050T
RATINGS
Limiting values in accordance with the Absolute Maximum System (IEC 134)
SO PACKAGE DESIGN EXAMPLE
To achieve the small dimension of the encapsulation the SO package is preferred with only 8 pins. Because a heatsink
is not applicable, the dissipation is limited by the thermal resistance of the 8-pin SO encapsulation until:
