TDA7294 part 2

The output power that the TDA7294 in highefficiency application is able to supply at Vs = + 40 V / + 20 V / – 20 V / – 40 V;  f = 1 kHz is:
– Pout = 150 W @ T.H.D. = 10 % with Rl = 4 Ω
– Pout = 120 W @ T.H.D. = 1 % with Rl = 4 Ω
– Pout = 100 W @ T.H.D. = 10 % with Rl = 8 Ω
– Pout = 80 W @ T.H.D. = 10 % with Rl = 8 Ω
Results from efficiency measurements (4 and 8 Ω loads, Vs = ± 40 V) are shown by figures. We have 3 curves: total power dissipation, power dissipation of the TDA7294 and power dissipation of the darlingtons.
