BD5426EFS

支持模擬輸入/BTL輸出的D類揚(yáng)聲器放大器; ? A high efficiency of 87% (9W + 9W output with 8Ω load), which is the highest grade in the industry and low heat-generation.\n? An output of 10W + 10W (13V, with 8Ω load) is allowed without an external heat radiator.\n? Driving a lowest rating load of 6Ω is allowed.\n? Pop noise upon turning power on/off and power interruption has been reduced.\n? High-quality audio muting is implemented by soft-switching technology.\n? An output power limiter function limits excessive output to speakers.\n? High-reliability design provided with built-in protection circuits against high temperatures, against VCC shorting and GND shorting, against reduced-voltage, and against applying DC voltage to speaker.\n8) A master/slave function allowing synchronization of multiple devices reduces beat noises.\n9) Adjustment of internal PWM sampling clock frequencies (250kHz to 400kHz) allows easy protective measures against unwanted radio emission to AM radio band.\n10) A compact back-surface heat radiation type power package is employed.\nHTSSOP-A44(5mm × 7.5mm × 1.0mm, pitch 0.8mm );

BD5426EFS是面向超薄電視等省空間、低發(fā)熱量用途的10W+10W立體聲D類功率放大器IC。\n\n采用先進(jìn)的BCD (Bipolar, CMOS and DMOS)工藝技術(shù)，將輸出功率段的導(dǎo)通電阻和接線電阻所產(chǎn)生的內(nèi)部損失減至極限，實(shí)現(xiàn)了87% (9W+9W 輸出,8Ω負(fù)載時(shí))的高效率。\n\n并采用小型背面散熱型功率封裝，具備低功耗、低發(fā)熱量，無需外接散熱器即可實(shí)現(xiàn)總體最大20W輸出。是同時(shí)滿足音響類系統(tǒng)大幅小型化、薄型化以及強(qiáng)感染力、高音質(zhì)播放兩方面需求的產(chǎn)品。
