TDA8950 general description:
TDA8950 Audio Amplifier 2x150W



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 Ω. 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. TDA8950 Audio Amplifier 2x150W


TDA8950 features:



  • Pin compatible with TDA8920B for both HSOP24 and DBS23P packages
