160W+160W dual BTL class D audio amplifier

Download Datasheet

The TDA7498E is a dual BTL class-D audio amplifier with a 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

  • 160-W + 160-W output power at THD = 10% with RL = 4 Ω and VCC = 36 V
  • 1 x 220 W output power mono parallel BTL at THD = 10% with RL = 3 Ω and VCC = 36 V
  • Wide-range single-supply operation (14 - 36 V)
  • High efficiency (η = 85%)
  • Parallel BTL function using the MODE pin
  • Four selectable, fixed gain settings of nominally 23.8 dB, 29.8 dB, 33.3 dB and 35.8 dB
  • Differential inputs minimize common-mode noise
  • Standby and mute features
  • Smart protection
  • Thermal overload protection
  • Small offset less than 20 mV
