Product Overview

The LTC1064CSW#PBF is a four high speed low noise switched-capacitor Filter Building Block for use with spectral analysis. Each filter building block, together with external clock and three to five resistors can provide various 2nd order functions like lowpass, highpass, bandpass and notch. The center frequency of each 2nd order function can be tuned with an external clock or a clock and resistor ratio. For Q <= 5, the center frequency range is from 0.1Hz to 100kHz. For Q <= 3, the center frequency range can be extended to 140kHz. Up 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 LTC1064 including internal thin film resistors can be obtained for high volume applications.
  • Customized version with internal resistors available
  • 7MHz Maximum clock frequency
  • Clock-to-center frequency ratio of 50:1 and 100:1 simultaneously available
  • Low offsets
