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:
