THERMAL RESISTANCE

Notes to the thermal resistance

TDA7052A: VP = 6 V; RL = 8 Ω. The maximum sine-wave dissipation is 0.9 W.

Therefore Tamb(max) = 150 − 100 × 0.9 = 60 °C.

TDA7052AT: VP = 6 V; RL = 16 Ω. The maximum sine-wave dissipation is 0.46 W.

Therefore Tamb(max) = 150 − 155 × 0.46 = 78 °C.
