National Semiconductor MF10 Universal Monolithic Dual Switched Capacitor Filter Datasheet
The National Semiconductor MF10 is a general-purpose CMOS active filter building block consisting of two independent sections. Each section can be configured with an external clock and three to four resistors to produce various 2nd order functions, including lowpass, bandpass, highpass, notch, or allpass responses. Up to 4th order functions are achievable by cascading the internal blocks or multiple packages.
The device operates up to 30 kHz with a clock-to-center frequency ratio accuracy of +0.6%. It is available in 20-pin Dual-In-Line and Surface Mount (SO) wide-body packages. The datasheet provides absolute maximum ratings, electrical characteristics for various supply voltages and temperatures, and typical performance curves regarding power supply current, output swing, Q deviation, and crosstalk.
