General Description
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.
