    The TDA7491LP 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 TDA7491LP is pin-to-pin compatible with the TDA7491P and TDA7491HV.

    Key features
    • 5 W + 5 W continuous output power:RL= 8 Ω, THD = 10% at VCC = 9 V
