50 W + 50 W dual BTL class-D audio amplifier

The TDA7492 is a dual BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors.

Thanks to the high efficiency and exposed-pad-up (EPU) package, only a simple heatsink is required.

Key Features

  • 50 W + 50 W continuous output power at THD = 10% with RL = 6 Ω and VCC = 25 V
  • 40 W + 40 W continuous output power at THD = 10% with RL = 8 Ω and VCC = 25 V
  • Wide-range single-supply operation (8 - 26 V)
  • High efficiency (η = 90%)
  • Four selectable, fixed gain settings of nominally 21.6 dB, 27.6 dB, 31.1 dB and 33.6 dB
  • Differential inputs minimize common-mode noise
  • Standby and mute features
  • Short-circuit protection
  • Thermal overload protection
  • Externally synchronizable
  • ECOPACK® , environmentally friendly package
