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.
