TDA7498MV:100-watt mono BTL class-D audio amplifier

The TDA7498MV is a mono BTL class-D audio amplifier with single power supply designed for home systems and active speaker applications.

It comes in a 36-pin PowerSSO package with exposed pad up (EPU) to facilitate mounting a separate heatsink.

Key Features

  • 100 W output power at THD = 10% with RL = 6 Ω and VCC = 36 V
  • 80 W output power at THD = 10% with RL = 8 Ω and VCC = 34 V
  • Wide-range single-supply operation (14 - 39 V)
  • High efficiency (η = 90%)
  • Four selectable, fixed gain settings of nominally 25.6 dB, 31.6 dB, 35.1 dB and 37.6 dB
  • Differential inputs minimize common-mode noise
  • Standby and mute features
  • Short-circuit protection
  • Thermal overload protection
  • Externally synchronizable
