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 resis-
tors, can produce various 2nd order functions. Each building
block has 3 output pins. One of the outputs can be config-
ured to perform either an allpass, highpass or a notch func-
tion; the remaining 2 output pins perform lowpass and band-
pass functions. The center frequency of the lowpass and
bandpass 2nd order functions can be either directly depen-
dent on the clock frequency, or they can depend on both
clock frequency and external resistor ratios. The center fre-
quency of the notch and allpass functions is directly depen-
dent on the clock frequency, while the highpass center fre-
quency 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 Butter-
worth, Bessel, Cauer and Chebyshev) can be formed.
For pin-compatible device with improved performance refer
to LMF100 datasheet.
