TDA8950
1. General description
The TDA8950 is a high-efficiency Class D audio power amplifier. The typical output power
is 2 ´ 150 W with a speaker load impedance of 4 W.
The TDA8950 is available in both HSOP24 and DBS23P power packages. The amplifier
operates over a wide supply voltage range from ±12.5 V to ±40 V and features low
quiescent current consumption.
2. Features
n Pin compatible with TDA8920B for both HSOP24 and DBS23P packages
n Symmetrical operating supply voltage range from ±12.5 V to ±40 V
n Stereo full differential inputs, can be used as stereo Single-Ended (SE) or mono
Bridge-Tied Load (BTL) amplifier
n High output power in typical applications:
u SE 2 ´ 150 W, RL = 4 W (VP = ±37 V)
u SE 2 ´ 170 W, RL = 4 W (VP = ±39 V)
