双通道、非常低噪声、差分放大器和 5MHz 低通滤波器

LT®6604-5 包含两个匹配的全差分放大器，它们各具有一个四阶、5MHz 低通滤波器。固定频率低通滤波器近似一个切比雪夫响应。通过集成一个滤波器和一个差分放大器，该器件实现了极低的失真和噪声。在单位增益条件下，测得的带内信噪比达到了令人注目的 82dB。在较高的增益条件下，输入参考噪声下降，于是，该器件能够处理较小的输入差分信号，而不会使信噪比发生显著的劣化。 两个通道之间的增益和相位完全匹配。每个通道的增益采用两个外部电阻器来独立地设置。通过提供一个可调的输出共模电压，LT6604-5 实现了电平移位，从而使其非常适合于直接连接至 ADC。LT6604-5 的技术规格针对 3V 工作电压 • 具5MHz低通滤波器的双通道差分放大器\n\n• 四阶滤波器\n\n• 近似切比雪夫 (Chebyshev) 响应\n\n• 保证相位和增益匹配\n\n• 可利用电阻器来设置的差分增益 \n\n\n\n\n• > 82dB信噪比 (3V 电源，2VP-P 输出) \n\n• 低失真 (1MHz，2VP-P 输出，800Ω 负载)\n• HD2：93dBc \n\n• HD3：96dBc \n\n\n\n\n• 针对采用 3V、5V 和 ±5V 工作电源拟订技术规格 \n\n• 全差分输入和输出 \n\n• 可调的输出共模电压 \n\n• 小外形 4mm x 7mm x 0.75mm QFN;
