LM48411 is a single-supply, high-efficiency, 2.5W/channel Class-D audio amplifier. Enhance LM48411 function National emission suppression (E 2 S) system, i.e. boasting a unique patent-pending ultra-low electromagnetic interference, spread-spectrum PWM structure that significantly reduces RF radiation while preserving audio quality and efficiency. My E 2 S system, improving battery life, reducing the number of external components, board area consumption, system cost, and simplifying design.

LM48411 is designed to meet the needs of mobile phones and other portable communication devices. Powered by a 5V supply, it is capable of delivering less than 10% THD+N 2.5W/channel continuous output power to a 4Ω load Its flexible power requirements allow operation from 2.4V to 5.5V. The LM48411 architecture of the broadband propagation spectrum reduces EMI radiation due to the frequency of the modulator.

LM48411 is highly efficient compared to 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 high-quality audio reproduction and high efficiency (η = 87% at V DD = 3.6 V, P O = 500MW). The four gain options GAIN0 and Gain 1 pins are pin-selected.

LM48411 has a low power consumption shutdown mode. Shutdown can enable the drive shutdown pin to Logical Low (GND).

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. Independent left/right shutdown control for hybrid mono/stereo applications maximizes power savings.
