带麦克风输入的单声道模数转换器 (ADC)

WM8950 是一款专为便携式应用（例如数码相机、数码录音笔或游戏控制台配件）设计的低功耗、高品质单声道模数转换器 (ADC)。该设备将对差分或单端麦克风的支持进行了集成。由于无需单独的麦克风放大器，因此降低了外部组件的需求。高级三角积分转换器与数字抽取滤波器结合使用，可在 8 至 48 ks/s 采样率下提供高品质音频。另外还提供额外的数字滤波选项，可以更好地应用滤波，例如风噪声消减、噪音抑制，还提供高级混合信号自动电平控制 (ALC) 功能和噪音门。提供片上 PLL，以便从外部参考时钟生成所需的主时钟。如果系统中的其他位置需要，也可采用 PLL 时钟为输出。WM8950 可在 2.5 至 ·可编程麦克风前置放大器增益\n·带共模抑制的伪差分输入\n·模数转换器 (ADC) 路径中有可编程自动电平控制 (ALC)/噪音门\n·5 波段 EQ\n·可编程高通滤波器（风噪声消减）\n·完全可编程 IIR 滤波器（陷波滤波器）\n·2.5 V 至 3.6 V（数字：1.71 V 至 3.6 V）\n·48 ks/s 全开模式下耗电量为 10 mA;
