The LM48410 is a single supply, high efficiency, 2.3W/channel, filterless switching audio amplifier. It eliminates the output filter, reducing external component count, board area consumption, system cost, and simplifying design. The device operates from a single 5V supply and delivers 2.3W/channel of continuous output power to a 4Ω load with less than 10% THD+N. It offers two logic selectable modulation schemes, fixed frequency mode, and an EMI suppressing spread spectrum mode. The LM48410 features high efficiency compared with conventional Class AB amplifiers. It includes National's 3D audio enhancement that improves stereo sound quality by affecting channel specialization and widening the perceived soundstage.
