10W立体声/15W单声道、无需滤波的扩频D类放大器

MAX9703/MAX9704单声道/立体声D类音频功率放大器以D类效率提供AB类放大器的性能，节省电路板空间，而且无需使用大型的散热装置。这两款器件采用D类结构，提供高达15W功率时效率高达78%。调制与开关方案可以省去传统D类放大器的输出滤波器。\n\n MAX9703/MAX9704有两种调制模式：固定频率模式(FFM)和扩频模式(SSM)，SSM模式降低了调制频率产生的EMI辐射。本器件使用完全差分结构、完全桥式输出和全面的杂音抑制。\n\n MAX9703/MAX9704具有80dB的高PSRR，0.07%的低THD+N和超过95dB的SNR。短路 • 无需滤波器的D类放大器\n• 独特的扩频模式比传统方法辐射降低5dB\n• 效率高达78% (RL = 8Ω)\n• 效率高达88% (RL = 16Ω)\n• 8Ω负载时可提供15W输出功率(MAX9703)\n• 8Ω负载时可提供2x10W输出功率(MAX9704)\n• 0.07%的低THD+N\n• 高PSRR (1kHz处为80dB)\n• 10V至25V单电源工作\n• 差分输入把共模噪声降到最小\n• 通过引脚选择增益减少了使用元件的数量\n• 业内领先的杂音抑制 \n• 低静态电流(24mA)\n• 低功耗关断模式(0.2µA)\n• 短路和热过载保;
