双路、通用开关电容滤波器

MAX7490/MAX7491由两个相同的低功耗、低电压、宽动态范围、轨到轨、二阶开关电容构建模块组成。两个滤波器部分各自都可以与两到四个外部电阻一起生成所有标准二阶函数：带通、低通、高通和陷波（带阻）。其中三个函数可同时使用。通过级联两个二阶滤波器部分可以组成四阶滤波器。同样，通过级联多个MAX7490/MAX7491可以轻松组成更高阶滤波器。\n\n 提供两种时钟选项：内置时钟（通过使用外部电容实现），或者外部时钟（用于实现更严格的截止频率控制）。时钟与中心频率比为100:1。采样以两倍时钟频率进行，可将截止频率和奈奎斯特频率进一步分离。\n\n MAX7490/MAX • 采用16引脚QSOP封装的双通道二阶滤波器\n\n• 高精度\n• Q精度：±0.2%\n\n• 时钟与中心频率误差：±0.2%\n\n\n\n\n• 轨到轨输入和输出操作\n\n• 单电源供电：+5V (MAX7490)或+3V (MAX7491)\n\n• 内部或外部时钟\n\n• 高通、低通、带通和陷波滤波器\n\n• 时钟与中心频率比为100:1\n\n• 内部采样与中心频率比为200:1\n\n• 中心频率高达40kHz\n\n• 轻松级联以组成多极滤波器\n\n• 低功耗关断：电源电流：< 1µA;
