LM48413 is a single-supply, high-efficiency, 1.2W/channel, filtered switching audio amplifier. Enhance the LM48413 function of national emission suppression (E 2 S) System - A unique patented ultra-low EMI, spread spectrum PWM architecture. It significantly reduces RF emissions while preserving the quality and efficiency of the audio. My E 2 S system, improving battery life, reducing the number of external components, board area consumption, system cost, and product design cycle time. LM48413TL is a miniature SMD package, which further saves space.

LM48413 is designed to meet the needs of mobile phones and other portable communication devices. The device operates from a single 5V supply and is capable of delivering less than 1% THD + N 1.2W/channel continuous output power to an 8Ω load Flexible power requirements allow operation from 2.4V to 5.5V. The LM48413 architecture of the broadband propagation spectrum reduces EMI radiation due to the frequency of the modulator.

LM48413 has a higher efficiency than traditional Class AB amplifiers. My E 2 The S system includes an advanced, patent-pending Edge Rate Control (ERC) architecture that further reduces emissions and minimizes the high-frequency component of the device's output, while maintaining its high-quality audio reproduction and high efficiency (η = 85% at V DD = 3.6V, P O = 500MW). LM48413 also includes a nationwide 3D sound enhancement that improves stereo sound quality. On the left, right speakers on approaching equipment, 3D enhancement influences channel specialization, expanding the perceived sound field.

Output short-circuit protection against damage to equipment under fault conditions. Advanced click suppression eliminates audible transient noise during power-up/power-off and shutdown. Shutdown control is also available to maximize power savings.
