LT LTC1164CN#PBF

Overview

The LTC1164CN consists of four low power, low noise 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.

The LTC1164CN is manufactured using our enhanced LTCMOS™ silicon gate process.
