高速、四通道、通用型滤波器单元式部件

LTC®1264 包括 4 个相同的高速、二阶开关式电容滤波器单元式部件，专为高达 250kHz 的中心频率而设计。每个单元式部件连同 3 到 5 个电阻器能够提供诸如低通、高通、带通和陷波等二阶滤波器功能。每个二阶部分的中心频率通过一个外部时钟进行调谐。时钟-中心频率比在内部设定为 20:1，但是可以通过外部电阻器来改变。\n\n LTC1264 的混叠性能通过对每个二阶部分进行双采样获得了改善。在将可检测到任何混叠分量之前，输入信号频率最高可达到时钟频率的两倍。\n\n 对于 Q ≤ 5 和 TA < 85°C，最大中心频率为 160kHz。对于 Q ≤ 2，最大中心频 • 高速，高达 250kHz 的中心频率\n\n• 4 个相同的滤波器整合在一个 0.3” 宽的封装中\n\n• 时钟-中心频率比为 20:1\n\n• 双采样，混叠性能有所改善\n\n• 采用 ±2.37V 至 ±8V 电源工作\n\n• 能提供具有可用内部电阻的定制版本\n\n• 低噪声\n\n• 低谐波失真\n\n• 可提供 24 引脚 DIP 和 SO 宽体封装\n\n\n;
