􀂾 Class-T architecture
􀂾 High Power
􀂾 100W @ 4Ω, 1.0% THD+N
􀂾 90W @ 4Ω, 0.1% THD+N
􀂾 60W @ 8Ω, 0.1% THD+N

TDA8920B
RL = 3 W; THD = 10 %; VP = ±27 V - 110 - W
RL = 4 W; THD = 10 %; VP = ±27 V - 86 - W

TDA8950
u SE 2 ´ 150 W, RL = 4 W (VP = ±37 V)
u SE 2 ´ 170 W, RL = 4 W (VP = ±39 V)
u SE 2 ´ 100 W, RL = 6 W (VP = ±37 V)
u BTL 1 ´ 300 W, RL = 8 W (VP = ±37 V)
