LTC1067IGN#PBF

LTC1067 is a rail-to-rail, very low noise universal dual filter building block. It consist of two identical rail-to-rail, high accuracy and very wide dynamic range 2nd order switched-capacitor building blocks. Each building block, together with three to five resistors, provides 2nd order filter functions such as bandpass, highpass, low pass, notch and all pass. High precision 4th order filters are easily designed. The centre frequency of each 2nd order section is tuned by the external clock frequency. This device have a double sampled architecture which places aliasing and imaging components at twice the clock frequency. It is widely used in application such as notch filters, narrowband bandpass filters, tone detection, noise reduction systems etc.
