  • The TDA7498 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.

    Key Features

    • 100 W + 100 W output power at THD = 10% with RL = 6 Ω and VCC = 36 V
    • 80 W + 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
