  • This page contains information on a product that is not recommended for new designs.

The TDA8950 is a high-efficiency Class D audio power amplifier. The typical output power is 2 x 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.

Product Details

Features

  • Pin compatible with TDA8920B for both HSOP24 and DBS23P packages
  • Symmetrical operating supply voltage range from +-12.5 V to +-40 V
  • Stereo full differential inputs, can be used as stereo Single-Ended (SE) or mono Bridge-Tied Load (BTL) amplifier
  • High output power in typical applications:
    • SE 2 x 150 W, RL = 4 Ω (VP = +-37 V)
    • SE 2 x 170 W, RL = 4 Ω (VP = +-39 V)
    • SE 2 x 100 W, RL = 6 Ω (VP = +-37 V)
    • BTL 1 x 300 W, RL = 8 Ω (VP = +-37 V)
  • Low noise
  • Smooth pop noise-free start-up and switch off
  • Zero dead time switching
  • Fixed frequency
  • Internal or external clock
  • High efficiency
  • Low quiescent current
  • Advanced protection strategy: voltage protection and output current limiting
  • Thermal FoldBack (TFB)
  • Fixed gain of 30 dB in SE and 36 dB in BTL applications
  • Fully short-circuit proof across load
  • BD modulation in BTL configuration

Target Applications

  • DVD
  • Mini and micro receiver
  • Home Theater In A Box (HTIAB) system
  • High-power speaker system
