TDA7491HV中文资料20W+20W双BTL D类音频放大器数据手册ST规格书

描述 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.
