  • The TDA7491P 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-down (EPD) package no separate heatsink is required.
    Furthermore, the filterless operation allows a reduction in the external component count.
    The TDA7491P is pin-to-pin compatible with the TDA7491LP and TDA7491HV.

    Key Features

    • 10 W + 10 W continuous output power:RL= 6 Ω, THD = 10% at VCC = 11 V
    • 9.5 W + 9.5 W continuous output power:RL= 8 Ω, THD = 10% at VCC = 12 V
    • Wide range single supply operation (5 V - 18 V)
    • High efficiency (η = 90%)
    • Four selectable, fixed gain settings of nominally 20 dB, 26 dB, 30 dB and 32 dB
    • Differential inputs minimize common-mode noise
    • Filterless operation
    • No ‘pop’ at turn-on/off
    • Standby and mute features
    • Short-circuit protection
    • Thermal overload protection
    • Externally synchronizable
