LTC1067/LTC1067-50 Rail-to-Rail, Very Low Noise Universal Dual Filter Building Block FEATURES s s s s s DESCRIPTION The LTC ®1067/LTC1067-50 consist of two identical railto-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 order filter functions such as bandpass, highpass, lowpass, notch and allpass.
High precision 4th order filters are easily designed.
The center frequency of each 2nd order section is tuned by 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 resisto...
