帶揚(yáng)聲器驅(qū)動器的 98/94 dB 單聲道編解碼器

WM8974 是一款低功率的單聲道編解碼器，集成對差分或單端麥克風(fēng)的支持，并包含適用于揚(yáng)聲器或耳機(jī)和單聲道線路輸出的驅(qū)動器。無需單獨的麥克風(fēng)和耳機(jī)放大器，而且高級的Delta-Sigma轉(zhuǎn)換器與數(shù)字抽取和插補(bǔ)濾波器結(jié)合使用，可在 8 至 48 ks/s 的采樣率下提供高品質(zhì)音頻。在模數(shù)轉(zhuǎn)換器 (ADC) 路徑中另有其他數(shù)字濾波選項，可提供“風(fēng)噪聲消減”等應(yīng)用濾波。還提供帶噪音門的高級混合信號自動電平控制 (ALC) 功能。提供片上 PLL，以便從外部參考時鐘生成所需的主時鐘。如果系統(tǒng)中的其他位置需要，也可采用 PLL 時鐘為輸出。芯片的不同部分還可通過使用可選的兩線或三線控制接口，在軟件控制下 ·單聲道編解碼器\n·音頻采樣率：8、11.025、16、22.05、24、32、44.1、48 kHz\n·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) @ 8 – 48 ks/s）\n·模數(shù)轉(zhuǎn)換器 (ADC) 信噪比 (SNR) 94 dB、總諧波失真 (THD) -83 dB（“A”加權(quán) @ 8 – 48 ks/s）\n·片上耳機(jī)/揚(yáng)聲器驅(qū)動器，采用“無電容”連接·16 W/3.3 V SPKVDD 下的輸出功率為 40 mW\n·橋接負(fù)載 (BTL) 揚(yáng)聲器驅(qū)動器 0.9 W，輸入至 8W / 5V SPKVDD\n\n·其他;
