LTC1067/LTC1067-50  
Rail-to-Rail, Very Low Noise  
Universal Dual Filter Building Block  
U
FEATURES  
DESCRIPTION  
The LTC®1067/LTC1067-50 consist of two identical rail-  
to-rail, high accuracy and very wide dynamic range 2nd  
order switched-capacitor building blocks. Each building  
block, together with three to five resistors, provides 2nd  
orderfilterfunctionssuchasbandpass,highpass,lowpass,  
notch and allpass. High precision 4th order filters are  
easily designed.  
■
Rail-to-Rail Input and Output Operation  
Operates from a Single 3V to ±5V Supply  
Dual 2nd Order Filter in a 16-Lead SSOP Package  
> 80dB Dynamic Range on Single 3.3V Supply  
Clock-to-Center Frequency Ratio of 100:1 for the  
LTC1067 and 50:1 for the LTC1067-50  
Internal Sampling-to-Center Frequency Ratio of  
200:1 for the LTC1067 and 100:1 for the LTC1067-50  
Center Frequency Error < ±0.2% Typ  
Low Noise: < 40µVRMS, Q ≤ 5  
Customizable with Internal Resistors

the external clock frequency. The internal clock-to-center  
frequency ratio (100:1 for the LTC1067 and 50:1 for the  
LTC1067-50) can be modified by the external resistors.  
These devices have a double sampled architecture which

frequency. The LTC1067-50 is a low power device con-  
suming about one half the current of the LTC1067. The  
LTC1067-50’s typical supply current is about 1mA from a  
3.3V supply.

Noise Reduction Systems  
The LTC1067 and LTC1067-50 are available in 16-pin  
narrow SSOP and SO packages.  
Mask programmable versions of the LTC1067 and  
LTC1067-50, with thin film resistors on-chip and custom  
clock-to-cutoff frequency ratios, can be designed in an  
SO-8 package to realize application specific monolithic  
filters. Please contact LTC Marketing for more details.
