Power dissipation
TDA7053A:
Assume VP = 6 V and RL = 8 Ω.
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 Ω.
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.
