BD5413EFV
支援類比輸入/BTL輸出的D類喇叭放大器
BD5413EFV是針對電動喇叭等低功耗、低發熱量用途而開發的5W+5W立體聲D類功率放大IC。採用頂尖的BCD (Bipolar, CMOS and DMOS)製程技術，將輸出功率段的導通電阻和接線電阻所產生的內部損失減至極限，實現了80% (4W+4W 輸出,8Ω負載時)的高效率。並採用小型背面散熱型功率封裝，具備低功耗、低發熱量，無需外接散熱器即可實現總體最大12.8W輸出。
是同時滿足音響類系統大幅小型化、薄型化以及強感染力、高音質播放兩方面需求的產品。

BD5413EFV is a 5W + 5W stereo class-D power amplifier specifically developed for low power consumption and low heat generation applications like powered speakers. BD5413EFV employs the state-of-the-art BCD (Bipolar, CMOS and DMOS) process technology to eliminate a turn-on resistance in the output power stage and an internal loss due to a wiring resistance as much as possible, achieving a high performance of 80% (4W + 4W output with a load resistance of 8Ω).
