TDA7498L - 80 watt + 80 watt dual BTL class-D audio amplifier

Description

The TDA7498L is a dual 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.

Features

  • 80 W + 80 W output power at THD = 10% with RL = 6 Ω and VCC = 32 V.
  • 70 W + 70 W output power at THD = 10% with RL = 8 Ω and VCC = 34 V.
  • Wide-range single-supply operation (14 - 36 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.
