MF6

6th Order Switched Capacitor Butterworth Lowpass

Filter

General Description

The MF6 is a versatile easy to use, precision 6th order But-

terworth lowpass active filter. Switched capacitor techniques

eliminate external component requirements and allow a

clock tunable cutoff frequency. The ratio of the clock fre-

quency to the lowpass cutoff frequency is internally set to 50

to 1 (MF6-50) or 100 to 1 (MF6-100). A Schmitt trigger clock

input stage allows two clocking options, either self-clocking

(via an external resistor and capacitor) for stand-alone appli-

cations, or an external TTL or CMOS logic compatible clock

can be used for tighter cutoff frequency control. The maxi-

mally flat passband frequency response together with a DC

gain of 1 V/V allows cascading MF6 sections for higher order

filtering. In addition to the filter, two independent CMOS op

amps are included on the die and are useful for any general

signal conditioning applications.
