... Up to 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 LTC1064 includ- ing internal thin film resistors can be obtained for high volume applications. Consult LTC Marketing for details. ...

... AGND (Pin 6): Analog Ground. When the LTC1064 oper- ates with dual supplies, Pin 6 should be tied to system ground. When the LTC1064 operates with a single positive supply, the analog ground pin should be tied to 1/2 supply and it should be bypassed with a 1µF solid tantalum in parallel with a 0.1µF ceramic capacitor, Figure 1. The ...

... Mode 1 is faster than Mode 3. Note that Mode 1 can only be implemented with three of the four LTC1064 sections because Section D has no externally available summing node. Section D, however, can be internally connected in Mode 1 upon special request ...

... Mode 3 is the second of the primary modes. In Mode 3, the ratio of the external clock frequency to the center fre- quency of each 2nd order section can be adjusted above or below 50:1 or 100:1. Side D of the LTC1064 can only be connected in Mode 3. Figure 6 illustrates Mode 3, the classical state variable configuration, providing highpass, bandpass and lowpass 2nd order filter functions ...
Page 10
... Mode 3a is more versatile than Mode 2 because the notch frequency can be higher or lower than the center fre- quency of the 2nd order section. The external op amp of Figure 9 is not always required. When cascading the sections of the LTC1064, the highpass and lowpass ...
