General description

The TDA8922C is a high-efficiency Class D audio power amplifier. Typical output power is 2 x 75 W with a speaker load impedance of 6 Ohm.

The TDA8922C is available in both HSOP24 and DBS23P power packages. The amplifier operates over a wide supply voltage range from +-12.5 V to +-32.5 V and features low quiescent current consumption.

Features

  • Pin compatible with TDA8950/20C for both HSOP24 and DBS23P packages
  • Symmetrical operating supply voltage range from +-12.5 V to +-32.5 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 75 W, RL = 6 Ohm (VDD = 30 V; VSS = -30 V)
    • SE 2 x 60 W, RL = 8 Ohm (VDD = 30 V; VSS = -30 V)
    • BTL 1 x 155 W, RL = 8 Ohm (VDD = 25 V; VSS = -25 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
