LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
THERMAL CHARACTERISTICS
Power dissipation
TDA7053A:
Assume VP= 6 V and RL=8Ω.
The maximum sine wave dissipation is 2 ×0.9 W = 1.8 W.
The Rth j-a of the package is 50 K/W therefore Tamb(max) = 150 −(50 ×1.8) = 60 °C.
TDA7053AT:
Assume VP= 6 V and RL=16Ω.
The maximum sine wave dissipation is 2 ×0.46 W = 0.92 W.
The Rth j-a of the package is 95 K/W therefore Tamb(max) = 150 −(95 ×0.92) = 62.6 °C.
