LMF100
High Performance Dual Switched Capacitor Filter
General Description
The LMF100 consists of two independent general purpose
high performance switched capacitor filters. With an external
clock and 2 to 4 resistors, various second-order and
first-order filtering functions can be realized by each filter
block. Each block has 3 outputs. One output can be config-
ured to perform either an allpass, highpass, or notch func-
tion. The other two outputs perform bandpass and lowpass
functions. The center frequency of each filter stage is tuned
by using an external clock or a combination of a clock and re-
sistor ratio. Up to a 4th-order biquadratic function can be re-
alized with a single LMF100. Higher order filters are imple-
mented by simply cascading additional packages, and all the
classical filters (such as Butterworth, Bessel, Elliptic, and
Chebyshev) can be realized.
The LMF100 is fabricated on National Semiconductor’s high
performance
analog
silicon
gate
CMOS
process,
LMCMOS
. This allows for the production of a very low off-
set, high frequency filter building block. The LMF100 is
pin-compatible with the industry standard MF10, but pro-
vides greatly improved performance.
