MF10 Universal Monolithic Dual Switched Capacitor Filter December 1994 MF10 Universal Monolithic Dual Switched Capacitor Filter General Description The MF10 consists of 2 independent and extremely easy to use general purpose CMOS active filter building blocks Each block together with an external clock and 3 to 4 resistors can produce various 2nd order functions Each building block has 3 output pins One of the outputs can be configured to perform either an allpass highpass or a notch function the remaining 2 output pins perform lowpass and bandpass functions The center frequency of the lowpass and bandpass 2nd order functions can be either directly dependent on the clock frequency or they can depend on both clock frequency and external resistor ratios The center frequency of the notch and allpass functions is directly dependent on the clock frequency while the highpass center frequency depends on both resistor ratio and clock Up to 4th order functions can be performed by cascading the two 2nd order building blocks of the MF10 higher than 4th order functions can be obtained by cascading MF10 packages Any of the classical filter configurations (such as Butterworth Bessel Cauer and Chebyshev) can be formed For pin-compatible device with improved performance refer to LMF100 datasheet Features Y Y Y Y Y Y Y Y Y Easy to use Clock to center frequency ratio accuracy g 0 6% Filter cutoff frequency stability directly dependent on external clock quality Low sensitivity to external component variation Separate highpass (or notch or allpass) bandpass lowpass outputs fO c Q range up to 200 kHz Operation up to 30 kHz 20-pin 0 3 wide Dual-In-Line package 20-pin Surface Mount (SO) wide-body package System Block Diagram Connection Diagram Surface Mount and Dual-In-Line Package TL H 10399 – 4 Top View Order Number MF10AJ or MF10CCJ See NS Package Number J20A Order Number MF10ACWM or MF10CCWM See NS Package Number M20B Order Number MF10ACN or MF10CCN See NS Package Number N20A TL H 10399 – 1 C1995 National Semiconductor Corporation TL H 10399 RRD-B30M115 Printed in U S A Absolute Maximum Ratings (Note 1) If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage (V a b Vb) Voltage at Any Pin Input Current at Any Pin (Note 2) Package Input Current (Note 2) Power Dissipation (Note 3) Storage Temperature ESD Susceptability (Note 11) 14V V a a 0 3V Vb b 0 3V 5 mA 20 mA 500 mW 150 C 2000V C C C C See AN-450 ‘‘Surface Mounting Methods and Their Effect on Product Reliability’’ (Appendix D) for other methods of soldering surface mount devices Soldering Information N Package 10 sec J Package 10 sec SO Package Vapor Phase (60 Sec ) Infrared (15 Sec ) 260 300 215 220 Operating Ratings (Note 1) Temperature Range MF10ACN MF10CCN MF10CCWM MF10ACWM MF10CCJ MF10AJ TMIN s TA s TMAX 0 C s TA s 70 C 0 C s TA s 70 C b 40 C s TA s 85 C b 55 C s TA s 125 C Ele.
