LMF100  
SNOSBG9B –JULY 1999–REVISED JUNE 2015  
LMF100 Dual High-Performance Switched Capacitor Filters  
Not Recommended for New Designs  
1 Features  
3 Description  
The LMF100 device consists of two independent  
general-purpose, high-performance switched

•
Wide 4-V to 15-V Power Supply Range  
Operation up to 100 kHz  
Low Offset Voltage:  
capacitor filters. With an external clock and two to  
four resistors, each filter block can realize various  
second-order and first-order filtering functions. Each  
block has three outputs. One output can be  
configured to perform either an allpass, highpass, or  
notch function. 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 resistor  
ratio. Up to a fourth-order biquadratic function can be  
realized with one LMF100. Higher order filters are  
implemented by simply cascading additional  
packages, and all the classical filters (such as  
Butterworth, Bessel, Elliptic, and Chebyshev) can be  
realized.

Vos1 = ±5 mV  
Vos2 = ±15 mV  
Vos3 = ±15 mV

Low Crosstalk: –60 dB  
Clock to Center Frequency Ratio Accuracy ±0.2%  
(Typical)

•
f0 × Q Range up to 1.8 MHz  
Pin-Compatible With MF10  
2 Applications  
The LMF100 is fabricated on TI’s high-performance  
analog silicon gate CMOS process, LMCMOS™. This  
allows for the production of a very low-offset, high-  
frequency filter building block. The LMF100 is pin-  
compatible with the industry standard MF10, but  
provides greatly improved performance.
