LTC1060CSW#PBF Datasheet PDF - Linear Technology

The LTC1060CSW#PBF is an Universal Dual Filter Building Block 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 lowpass, bandpass, highpass notch and allpass. The center frequency of these functions can be tuned by an external clock or by an external clock and resistor ratio. Up to 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. The LTC1060 operates with either a single or dual supply from ±2.37 to ±8V. When used with low supply (i.e. single 5V supply), the filter typically consumes 12mW and can operate with center frequencies up to 10kHz. With ±5V supply, the frequency range extends to 30kHz and very high Q values can also be obtained.
