LMF100  
High Performance Dual Switched Capacitor Filter  
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.  
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.
