LTC1164 Low Power, Low Noise, Quad Universal Filter Building Block
FEATURES

Low Power 4 Filters a 0.3" Wide Package 1/2 the Noise of the 60, 61 Devices Wide Output Swing Clock-to-Center Frequency Ratios of 50:1 and 100:1 Operates from to 8V Power Supplies Customized Version with Internal Resistors Available Ratio of 50:1 and 100:1 Simultaneously Available

Antialiasing Filters Telecom Filters Spectral Analysis Loop Filters For Fixed Lowpass Filter Requirements use the LTC1164-XX Series

The LTC1164 consists of four low power, low noise 2nd order switched capacitor filter building blocks. Each building block typically consumes 850A supply current. Low power is achieved without sacrificing noise and distortion. Each building block, together with to 5 resistors, can provide 2nd order functions like lowpass, highpass, bandpass, and notch. The center frequency of each 2nd order section can be tuned with an external clock, or a clock and resistor ratio. For < 5, the center frequency range is from to 8th order filters can be realized by cascading all four 2nd order sections. Any classical filter realization (such as Butterworth, Cauer, Bessel, and Chebyshev) can be formed. A customized monolithic version of the LTC1164 including internal thin film resistors can be obtained. Consult LTC Marketing for details. The LTC1164 is manufactured using Linear Technology's enhanced LTCMOSTM silicon gate process.
