4.7W防削頂單聲道D類(lèi)音頻功率放大器

HT6872是一款低EMI的，防削頂失真的，單聲道免濾波D類(lèi)音頻功率放大器。在6.5V電源，10% THD+N，4Ω負(fù)載條件下，輸出4.7W功率，在各類(lèi)音頻終端應(yīng)用中維持高效率并提供AB類(lèi)放大器的性能。\n\nHT6872的最大特點(diǎn)是防削頂失真（ACF）輸出控制功能，可檢測(cè)并抑制由于輸入音樂(lè)、語(yǔ)音信號(hào)幅度過(guò)大所引起的輸出信號(hào)削頂失真（破音），也能自適應(yīng)地防止在電池應(yīng)用中由電源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(tīng)音享受，并保護(hù)揚(yáng)聲器免受過(guò)載損壞。同時(shí)芯片具有ACF-Off?模式。\n\nHT6872具有獨(dú)有的電磁輻射（EMI）抑制技術(shù)和優(yōu)異的全帶寬低輻射性能，輻射水平 ? 防削頂失真功能(Anti-Clipping Function, ACF)\n? 優(yōu)異的全帶寬EMI抑制性能\n? 免濾波器數(shù)字調(diào)制，直接驅(qū)動(dòng)揚(yáng)聲器\n? 輸出功率1.40W (VDD=3.6V, RL=4?, THD+N=10%)2.80W (VDD=5.0V, RL=4?, THD+N=10%)4.70W (VDD=6.5V, RL=4?, THD+N=10%)\n? 高信噪比SNR：95dB (VDD?=?6.5V,?Av?=?24dB, THD+N = 1%)\n? 低靜態(tài)電流Input AC Grounded, Without Load2.65mA?;
