Nuvoton’s smart amp device combines our standard Class D amplifier with V/I sense ADCs to support the speaker protection algorithm, which can prevent the speaker membrane excursion from exceeding its rated limit and also provides ample headroom for overall loudness and sound quality.  Target applications for this device include mobile devices such as smartphones, tablet computers, laptops, and smart speakers, where small and thin speakers are essential.
