用于便携式音频应用的超低功耗编解码器

WM8904 是一款高性能、超低功耗的立体声编解码器，具有立体声接地参考耳机放大器，采用双模电荷泵架构，可优化回放过程中的效率和耗电量。接地参考耳机和线路输出可消除 AC 耦合电容器，而且两路输出都包括共模反馈路径以抑制本底噪音。用于音频路径设置的控制音序可通过集成控制写入音序器预先加载和执行，以减少软件驱动器开发并最大限度地减少砰噗声和喀哒声。模拟输入级可为单端或差分输入配置。可以连接最多三个立体声麦克风或线路输入。输入阻抗与可编程增益放大器 (PGA) 增益设置保持一致。提供立体声数字麦克风接口，具有两种可选输入。动态范围控制器提供压缩和电平控制，以支持广泛的便携式录制应用。防削波和快速断 • 耳机播放时数模转换器 (DAC) 的静态耗电量为 3.0 mW\n• 模拟旁路回放的静态耗电量为 2.4 mW\n• 数模转换器 (DAC) 信噪比 (SNR) 96 dB（典型值），总谐波失真 (THD) -86 dB（典型值）\n• 模数转换器 (ADC) 信噪比 (SNR) 91 dB（典型值），总谐波失真 (THD) -80 dB（典型值）\n• 控制写入音序器，可最大限度地减少启动和关闭时的砰噗声\n• 默认启动顺序的单个寄存器写入\n• 集成的 FLL 提供所有必需时钟• 自同步模式使处理器能够休眠\n• 8 kHz 至 96 kHz 的所有标准采样率\n\n• 立体声数字麦克;
