內(nèi)置BOOST升壓 D/AB 類音頻功率放大器

HT8691是一款內(nèi)置BOOST升壓模塊的D類音頻功率放大器。內(nèi)置的BOOST升壓模塊可通過外置電阻調(diào)節(jié)升壓值，即使是鋰電池供電，在升壓至6.5V時，10% THD+N，4Ω負載條件下能連續(xù)輸出5.5?W功率;升壓至7V，3Ω負載條件下則能連續(xù)輸出7.0W功率。其支持外部設(shè)置調(diào)節(jié)BOOST輸出電壓。\n\nHT8691的最大特點是防削頂失真（ACF）輸出控制功能，可檢測并抑制由于輸入音樂、語音信號幅度過大所引起的輸出信號削頂失真（破音），也能自適應(yīng)地防止在BOOST升壓電壓下降所造成的輸出削頂，顯著提高音質(zhì)，創(chuàng)造非常舒適的聽音享受，并保護揚聲器免受過載損壞。同時芯片具有ACF-Off? ?防削頂失真功能(防破音, Anti-Clipping Function, ACF)\r\n?免濾波器數(shù)字調(diào)制，直接驅(qū)動揚聲器\r\n?輸出功率\r\n5.5W (VBAT=4.2V, PVDD = 6.5V, RL=4?, THD+N=10%)\r\n7.0W (VBAT=4.2V, PVDD = 7.0V, RL=3?, THD+N=10%)\r\n3.0W (VBAT=4.2V, PVDD = 6.5V, RL=8?, THD+N=10%)\r\n?電源\r\n -升壓輸入VBAT：2.5V至5.5V\r\n -升壓輸出PVDD：VBAT至7.5V\r\n?BOO;
