帶麥克風(fēng)輸入的單聲道模數(shù)轉(zhuǎn)換器 (ADC)

WM8950 是一款專為便攜式應(yīng)用（例如數(shù)碼相機(jī)、數(shù)碼錄音筆或游戲控制臺(tái)配件）設(shè)計(jì)的低功耗、高品質(zhì)單聲道模數(shù)轉(zhuǎn)換器 (ADC)。該設(shè)備將對(duì)差分或單端麥克風(fēng)的支持進(jìn)行了集成。由于無(wú)需單獨(dú)的麥克風(fēng)放大器，因此降低了外部組件的需求。高級(jí)三角積分轉(zhuǎn)換器與數(shù)字抽取濾波器結(jié)合使用，可在 8 至 48 ks/s 采樣率下提供高品質(zhì)音頻。另外還提供額外的數(shù)字濾波選項(xiàng)，可以更好地應(yīng)用濾波，例如風(fēng)噪聲消減、噪音抑制，還提供高級(jí)混合信號(hào)自動(dòng)電平控制 (ALC) 功能和噪音門。提供片上 PLL，以便從外部參考時(shí)鐘生成所需的主時(shí)鐘。如果系統(tǒng)中的其他位置需要，也可采用 PLL 時(shí)鐘為輸出。WM8950 可在 2.5 至 ·可編程麥克風(fēng)前置放大器增益\n·帶共模抑制的偽差分輸入\n·模數(shù)轉(zhuǎn)換器 (ADC) 路徑中有可編程自動(dòng)電平控制 (ALC)/噪音門\n·5 波段 EQ\n·可編程高通濾波器（風(fēng)噪聲消減）\n·完全可編程 IIR 濾波器（陷波濾波器）\n·2.5 V 至 3.6 V（數(shù)字：1.71 V 至 3.6 V）\n·48 ks/s 全開(kāi)模式下耗電量為 10 mA;
