General description

The TDA8920B is a high efficiency class-D audio power amplifier with very low dissipation. The typical output power is 2 x 100 W.

The device is available in the HSOP24 power package and in the DBS23P through-hole power package. The amplifier operates over a wide supply voltage range from +-12.5 V to +-30 V (+-32 V non operating) and consumes a very low quiescent current.

Features

  • Zero dead time switching
  • Advanced current protection: output current limiting
  • Smooth start-up: no pop noise due to DC offset
  • High efficiency
  • Operating supply voltage from +-12.5 V to +-30 V
  • Low quiescent current
  • Usable as a stereo Single-Ended (SE) amplifier or as a mono amplifier in Bridge-Tied Load (BTL)
  • Fixed gain of 30 dB in Single-Ended (SE) and 36 dB in Bridge-Tied Load (BTL)
  • High output power
  • High supply voltage ripple rejection
  • Internal switching frequency can be overruled by an external clock
  • Full short-circuit proof across load and to supply lines
  • Thermally protected
