LTC1064CSW#PBF

LTC1064 is a quad channel, high speed, low noise switched-capacitor filter building blocks. Each filter building block, together with an external clock and three to five resistors can provide various 2nd order functions like low pass, high pass, bandpass and notch. The centre frequency of each 2nd order function can be tuned with an external clock, or a clock and resistor ratio. For Q ≤ 5, the centre frequency range is from 0.1Hz to 100KHz. For Q ≤3, the centre frequency range can be extended to 140KHz. Upto 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 device including internal thin film resistors can be obtained for high volume applications. It is used in application like anti-aliasing filters, wide frequency range tracking filters, spectral analysis, loop filters etc.
