DESCRIPTION
The MF10-N 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-N; higher than 4th order functions can be
obtained by cascading MF10-N 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.
