时间： 2021-07-19 来源：屹晶微电子

技术问答

屹晶微电子的EG8403 立体声D类音频功率放大器能够以D类放大器的效率提供AB类功率放大器的性能。采用低噪声，无滤波器结构可以省去传统D类放大器的输出低通滤波器。需要极少的外围元件，从而节省PCB的空间和系统成本，是便携式应用的理想选择。EG8403D类立体声音频功放能够以高于85%的效率提供3W功率，同时具有系统关断及静音控制功能。特殊的线路架构增强了抗噪声能力，减少了射频干扰。

芯片特点：

• 无滤波器的D类放大器，低静态电流和低EMI

• 在4Ω负载和5V电源条件下，提供高达3W输出功率

• 高达90%

• 低THD，低噪声

• 短路电流保护

• 热保护

• 极少的外围元器件，节省空间和成本

• 封装形式：SOP16无铅封装

应用领域：

• LCD电视、监视器

• 笔记本电脑

• 手机/免提电话

• 便携式DVD播放器，游戏机
