WM8940

帶揚聲器驅(qū)動器的 98/94 dB 單聲道編解碼器

WM8940 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的支持，并包含適用于揚聲器或耳機和單聲道線路輸出的驅(qū)動器。高級 Delta Sigma 轉(zhuǎn)換器與數(shù)字抽取及內(nèi)插濾波器組合使用，可在 8 至 48 ks/s 采樣率下提供高品質(zhì)音頻。模數(shù)轉(zhuǎn)換器 (ADC) 路徑中具有一個可選的高通濾波器和四個可完全編程的陷波濾波器。提供帶噪音門的高級混合信號自動電平控制 (ALC) 功能，同時支持在自動電平控制 (ALC) 操作期間回讀可編程增益放大器 (PGA) 增益。數(shù)字音頻接口支持 A-law 和 μ-law 壓擴。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; ? 音頻采樣率：8 至 48 kHz\n? 支持差分或單端麥克風\n? 片上 PLL\n? 2.5 V 至 3.6 V（數(shù)字電源電壓：1.71 V 至 3.6 V）\n? 4x4 mm 方形扁平無引腳封裝 (QFN)\n;
