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:

Supply voltage VPmax. 6 V

Peak output current IOM max. 150 mA

Total power dissipation see derating curve Fig.1

Storage temperature range Tstg −55 to +150 °C

Crystal temperature Tcmax. 100 °C

A.C. and d.c. short-circuit duration

at VP= 3,0 V (during mishandling) tsc max. 5 s
