Additional preview pages of the MF4 datasheet.

The MF4 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.
