TDA7491HV Datasheet (STMicroelectronics) - 20 W + 20 W dual BTL class-D audio amplifier

TDA7491HV, 20 W + 20 W dual BTL class-D audio amplifier

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.
