The TDA7491P is a dual BTL class-D audio amplifier with high efficiency, wide voltage operating range, and selectable gain settings. It is designed for LCD TVs and monitors, eliminating the need for a separate heatsink.
The TDA7491P is a dual bridge-tied load (BTL) Class-D audio amplifier designed for use in LCD TVs and monitors. It features high efficiency up to 90% and operates over a wide voltage range from 5 V to 18 V. The device supports filterless operation, which reduces the external component count by eliminating the need for output reconstruction filters.
