帶揚(yáng)聲器驅(qū)動器的 98/95 dB 立體聲編解碼器

WM8978 是一款低功率的立體聲編解碼器，帶有適用于立體聲差分麥克風(fēng)的集成式前置放大器，并包含適用于揚(yáng)聲器、耳機(jī)和差分或立體聲線路輸出的驅(qū)動器。由于無需單獨(dú)的麥克風(fēng)或耳機(jī)放大器，因此降低了外部元件的需求。高級片上數(shù)字信號處理功能包括五波段均衡器、用于通過模/數(shù)轉(zhuǎn)換器的麥克風(fēng)或線路輸入的混合信號自動電平控制，以及用于錄制或回放的純數(shù)字限制器功能。在模數(shù)轉(zhuǎn)換器 (ADC) 路徑中另有其他數(shù)字濾波選項(xiàng)，可提供“風(fēng)噪聲消減”等應(yīng)用濾波。WM8978 編解碼器可作為主要器件或從屬器件運(yùn)行。內(nèi)部 PLL 可基于通用的參考時鐘頻率（例如 12 和 13 MHz）為編解碼器生成所有所需音頻時鐘。芯片的個別部 立體聲編解碼器：·數(shù)模轉(zhuǎn)換器 (DAC) 信噪比 (SNR) 98 dB，總諧波失真 (THD) - 84 dB（“A”加權(quán) @ 48 kHz）\n·模數(shù)轉(zhuǎn)換器 (ADC) 信噪比 (SNR) 95 dB，總諧波失真 (THD) - 84 dB（“A”加權(quán) @ 48 kHz）\n·帶“無電容”選項(xiàng)的片上耳機(jī)驅(qū)動器\n·16 W/3.3 V SPKVDD 下的輸出功率為 40 mW\n·8 W 橋接負(fù)載 (BTL) 揚(yáng)聲器/5 V SPKVDD 下的輸出功率為 1 W\n·能夠驅(qū)動壓電揚(yáng)聲器\n·立體聲揚(yáng)聲器驅(qū)動器配置\n麥克風(fēng)前置放大器：·立體聲差分或單聲道麥克風(fēng)接口\n·可編程前置放大器增益;
