LTC1060CN#PBF

LTC1060 is a universal dual filter building block. This device consists of two high performance, switched capacitor filters. Each filter, together with 2 to 5 resistors, can produce various 2nd order filter functions such as low pass, bandpass, high pass notch and all pass. The centre frequency of these functions can be tuned by an external clock or by an external clock and resistor ratio. Upto 4th order full biquadratic functions can be achieved by cascading the two filter blocks. Any of the classical filter configurations (like butterworth, chebyshev, bessel, cauer) can be formed. It is used in application such as single 5V supply medium frequency filters, very high Q and High dynamic range bandpass, notch filters, tracking filters, telecom filters etc.
