Universal Filter Building Block
DESCRIPTIO
The LTC
2nd order switched capacitor filter building blocks. Each
building block typically consumes 850µA supply current.
Low power is achieved without sacrificing noise and
distortion. Each building block, together with 3 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 Q < 5, the center frequency
range is from 0.1Hz to 20kHz. 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 LTC1164
including internal thin film resistors can be obtained.
Consult LTC Marketing for details.
The LTC1164 is manufactured using Linear Technology’s
enhanced LTCMOS
