This circuit shows an LTC1062 and an LT1056 connected to form a notch filter. Figure 7-17B shows the frequency response for a 25-Hz notch filter using values based on the equations of Fig. 7-17A. The optional R2/C2 at the LTC1062 output is used to minimize clock feedthrough. The 1/(6.28R2C2) value should be 12 to 15 times that of the notch frequency.
