Product Summary
The MF4CN100 is a versatile, easy to use, precision 4th order Butterworth low-pass filter. Switched-capacitor techniques eliminate external component requirements and allow a clock-tunable cutoff frequency. The ratio of the clock frequency to the low-pass cutoff frequency is internally set to 50 to 1 (MF4-50) or 100 to 1 (MF4-100). A Schmitt trigger clock input stage of The MF4CN100 allows two clocking options, either selfclocking (via an external resistor and capacitor) for standalone applications, or for tighter cutoff frequency control an external TTL or CMOS logic compatible clock can be applied. The maximally flat passband frequency response together with a DC gain of 1 V/V allows cascading The MF4CN100 sections together for higher order filtering.
