八阶、低通、椭圆函数、开关电容滤波器

MAX293/MAX294/MAX297均为易于使用的8阶低通、椭圆、开关电容滤波器，其转折频率可设置为0.1Hz至25kHz (MAX293/MAX294)或0.1Hz至50kHz (MAX297)。\n\n MAX293/MAX297的变迁比为1.5，提供急剧的滚降和-80dB的阻带抑制。MAX294的变迁比为1.2，提供陡峭的滚降和-58dB的阻带抑制。所有三个滤波器都有固定的响应，因此设计任务仅限于选择控制滤波器转折频率的时钟频率。\n\n 外部电容用于使用内部振荡器产生时钟，也可以使用外部时钟信号。提供了一个非专用运算放大器（同相输入接地），用于构建后置滤波或抗混 • 8阶低通椭圆滤波器\n\n• 时钟可调转折频率范围：\n• 0.1Hz至25kHz (MAX293/MAX294)\n\n• 0.1Hz至50kHz (MAX297)\n\n\n\n\n• 无需外部电阻或电容\n\n• 内部或外部时钟\n\n• 时钟与转折频率比\n• 100:1 (MAX293/MAX294)\n\n• 50:1 (MAX297)\n\n\n\n\n• 采用+5V单电源或±5V双电源供电\n\n• 用于抗混叠或时钟噪声滤波的非专用运算放大器\n\n• 8引脚DIP和16引脚宽体SO封装;
