LMF60 General Description

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.
