The LMF60 is a high performance precision 6th-order Butterworth lowpass active filter It is fabricated using National's LMCMOS process an improved silicon-gate CMOS process specifically designed for analog products Switchedcapacitor 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 1 (LMF60-50) or 100 1 (LMF60-100) A Schmitt trigger clock input stage allows two clocking options either self-clocking (via an external resistor and capacitor) for stand-alone applications or for tighter cutoff frequency control a TTL or CMOS logic compatible clock can be directly applied The maximally flat passband frequency response together with a DC gain of 1V V allows cascading LMF60 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 The LMF60 is pin- and functionally-compatible with the MF6 but provides improved performance |
