BD5413EFV中文资料支持模拟输入/BTL输出的D类扬声器放大器数据手册ROHM规格书

描述 Description

BD5413EFV是针对电动扬声器等低功耗、低发热量用途而开发的5W+5W立体声D类功率放大器IC。采用先进的BCD (Bipolar, CMOS and DMOS)工艺技术，将输出功率段的导通电阻和接线电阻所产生的内部损失减至极限，实现了80% (4W+4W 输出,8Ω负载时)的高效率。并采用小型背面散热型功率封装，具备低功耗、低发热量，无需外接散热器即可实现总体最大12.8W输出。

是同时满足音响类系统大幅小型化、薄型化以及强感染力、高音质播放两方面需求的产品。
