Product overview

Description

The TDA7491HV 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) and down (EPD) packages, no separate heatsink is required.
The TDA7491HV is pin-to-pin compatible with the TDA7491P and TDA7491LP.
  • All features

    • 20 W + 20 W continuous output power:
      • RL = 8 Ω, THD = 10% at VCC = 18 V
    • Wide-range single-supply operation (5 - 18 V)
    • High efficiency (η = 90%)
    • Four selectable, fixed gain settings of nominally 20 dB, 26 dB, 30 dB and 32 dB
    • Differential input minimize common-mode noise
    • No ‘pop’ at turn-on/off
    • Standby and mute features
    • Short-circuit protection
    • Thermal overload protection
    • External synchronisation
