带耳机驱动器的超低功耗数/模转换器

WM8912 是一款超低功耗立体声数/模转换器 (DAC)，配备带有双模电荷泵的接地参考耳机放大器，可优化回放的效率和耗电量。接地参考输出无需耳机耦合电容器，而且输出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。WM8912 可直接由单个 1.8 V 开关电源供电，数字核心也可由 1.0 V 电源供电，实现最佳耗电量。 ·数模转换器 (DAC) 耳机播放静态耗电量较低，为 3.8 mW\n·W 类接地参考耳机驱动器\n·每声道 28 mW 时 30 Ω（总谐波失真 (THD) <1%）\n·每声道 32 mW 时 15 Ω（总谐波失真 (THD) <1%）\n·动态范围控制器\n·重调移动参数均衡器\n·片上 FLL 提供所有必需的时钟\n·32 引脚方形扁平无引脚封装 (QFN);
