A second-order Butterworth low-pass filter can be implemented  
using the AD825 as shown in Figure 33. The extremely low bias  
currents of the AD825 allow the use of large resistor values and,  
consequently, small capacitor values without concern for  
developing large offset errors. Low current noise is another  
factor in permitting the use of large resistors without having to  
worry about the resultant voltage noise.

With the values shown, the corner frequency will be 1 MHz.  
The equations for component selection are shown below. Note  
that the noninverting input (and the inverting input) has an  
input capacitance of 6 pF. As a result, the calculated value of C1  
(12 pF) is reduced to 6 pF.
