具有低RF干擾敏感度的單聲道音頻子系統(tǒng)，帶有DirectDrive耳機放大器

MAX9875集成了高效D類音頻功率放大器和立體聲AB類耳機放大器，耳機放大器采用無需電容的DirectDrive?架構。作為Maxim的第三代無需濾波的D類放大器，帶有有源輻射抑制功能，能夠以D類放大器的效率提供AB類放大器的優(yōu)異性能。\n 采用3.7V供電時，MAX9875能夠以87%的效率為8Ω負載提供高達725mW的功率，有效延長電池壽命。無濾波調(diào)制方案采用有源輻射抑制電路和擴頻調(diào)制技術，大大降低了EMI干擾，省去了傳統(tǒng)D類放大器所需的輸出濾波器。\n MAX9875內(nèi)部的立體聲AB類耳機放大器采用Maxim的DirectDrive技術，單電源供電時能夠產(chǎn)生以地為參考的輸出，無 \n? 低輻射、無濾波D類放大器能夠滿足EN55022 B類標準，并留有大于10dB的裕量 \n? 極低的RF敏感度，可有效抑制GSM無線網(wǎng)絡的TDMA噪聲 \n? 按照用戶自定義的輸入模式提供輸入混音 \n? 725mW揚聲器輸出(RSPK = 8Ω，PVDD = 3.7V) \n? 53mW耳機輸出(RHP = 16Ω，VDD = 3.7V) \n? 1kHz時，THD+N低至0.05% (D類功放) \n? 1kHz時，THD+N低至0.016% (耳機放大器) \n? 效率高達87% (RSPK = 8Ω，POUT = 750mW) \n? 揚聲器放大器具有較高;
