General Features

  • Pin compatible with TDA8950/20B 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
  • 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

High Output Power in Typical Applications

  • SE 2 x 110 W, RL = 4 Ω (VP = +-30 V)
  • SE 2 x 125 W, RL = 4 Ω (VP = +-32 V)
  • SE 2 x 120 W, RL = 3 Ω (VP = +-29 V)
  • BTL 1 x 220 W, RL = 8 Ω (VP =+-30 V)

Target Applications

  • DVD
  • Mini and micro receiver
  • Home theater in a box (HTIAB) system
