illustrate

LM48413是一个单电源,效率高,1.2W/channel,滤波器的开关音频放大器。 增强LM48413功能国家排放抑制(E 2 S)系统 - 一种独特的专利超低EMI,扩频PWM架构。 它大大降低了射频发射,同时保留了音频的质量和效率。 My E 2 S系统,提高电池寿命,减少外部元件数量,电路板面积消耗,系统成本和产品设计周期时间。 LM48413TL是一个微型SMD封装,进一步节省了空间。

LM48413是专为满足手机和其它便携式通信设备的需求。 设备是从单一5V电源工作,能够向8Ω负载提供连续输出功率小于1%THD + N 1.2W/channel Flexible power requirements allow operation from 2.4V to 5.5V. 宽带传播频谱的LM48413架构降低了EMI辐射由于调制器的频率。

LM48413具有效率高,比传统的AB类放大器。 My E 2 S系统包括一个先进的,正在申请专利的边沿速率控制(ERC)的体系结构,进一步降低排放量,最大限度地降低器件的输出的高频成分,同时保持其高品质的音频再现和高效率(η= 85%在VDD=3.6V,PO = 500MW)。 LM48413还包括全国的3D音效增强,提高了立体声音质。 在左,右扬声器在接近的设备,3D增强影响频道专业化,扩大感知的声场。

Output short-circuit protection against damage to the device under fault conditions. Advanced click suppression eliminates audible transient noise when powering up/down and shutting down. 还提供关断控制,以最大限度地节省功耗。
