Description

Description

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.

  • All 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
