DESCRIPTIO
The LTC
switched-capacitor filter building blocks. Each filter build-
ing block, together with an external clock and three to five
resistors can provide various 2nd order functions like
lowpass, highpass, bandpass and notch. The center fre-
quency 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 includ-
ing internal thin film resistors can be obtained for high
volume applications. Consult LTC Marketing for details.
