The TDA7491MV is a mono BTL class-D audio amplifier designed for LCD TVs and monitors. It features high efficiency, wide range single supply operation, four selectable gain settings, and differential inputs.
The TDA7491MV is a mono BTL Class-D audio amplifier designed for single power supply operation, specifically targeting LCD TVs and monitors. It features high efficiency (up to 90%) and filterless operation to reduce external component count. The device includes an exposed-pad-down (EPD) package, eliminating the need for a heatsink in many applications.
