带扬声器驱动器的 98/95 dB 立体声编解码器

WM8978 是一款低功率的立体声编解码器，带有适用于立体声差分麦克风的集成式前置放大器，并包含适用于扬声器、耳机和差分或立体声线路输出的驱动器。由于无需单独的麦克风或耳机放大器，因此降低了外部元件的需求。高级片上数字信号处理功能包括五波段均衡器、用于通过模/数转换器的麦克风或线路输入的混合信号自动电平控制，以及用于录制或回放的纯数字限制器功能。在模数转换器 (ADC) 路径中另有其他数字滤波选项，可提供“风噪声消减”等应用滤波。WM8978 编解码器可作为主要器件或从属器件运行。内部 PLL 可基于通用的参考时钟频率（例如 12 和 13 MHz）为编解码器生成所有所需音频时钟。芯片的个别部 立体声编解码器：·数模转换器 (DAC) 信噪比 (SNR) 98 dB，总谐波失真 (THD) - 84 dB（“A”加权 @ 48 kHz）\n·模数转换器 (ADC) 信噪比 (SNR) 95 dB，总谐波失真 (THD) - 84 dB（“A”加权 @ 48 kHz）\n·带“无电容”选项的片上耳机驱动器\n·16 W/3.3 V SPKVDD 下的输出功率为 40 mW\n·8 W 桥接负载 (BTL) 扬声器/5 V SPKVDD 下的输出功率为 1 W\n·能够驱动压电扬声器\n·立体声扬声器驱动器配置\n麦克风前置放大器：·立体声差分或单声道麦克风接口\n·可编程前置放大器增益;
