TDA7053A
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
THERMAL CHARACTERISTICS
Power dissipation
TDA7053A:
Assume VP = 6 V and RL =8 .
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 =16 .
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.
