Product Overview

The LTC1067CS#PBF is an Universal Dual Filter Building Block, consists of two identical rail-to-rail high accuracy and very wide dynamic range 2nd Order switched-capacitor building block for use with tone detection. Each building block, together with three to five resistors, provides 2nd order filter functions such as bandpass, highpass, lowpass, notch and allpass. High precision 4th order filters are easily designed. The center frequency of each 2nd order section is tuned by the external clock frequency. The internal clock-to-center frequency ratio (100:1 for the LTC1067 and 50:1 for the LTC1067-50) can be modified by the external resistors. These devices have a double sampled architecture which places aliasing and imaging components at twice the clock frequency. The LTC1067-50 is a low power device consuming about one half the current of the LTC1067. The LTC1067-50's typical supply current is about 1mA from a 3.3V supply.
  • Operates from a single 3 to ±5V supply
  • <±0.2% Typical center frequency error
  • <40µVRMS, Q
  • Customizable with internal resistors
