EIGHT-POLE SALLEN KEY LOW-PASS FILTER
The AD862x’s high input impedance and dc precision make it a
great selection for active filters. Due to the very low bias current
of the AD862x, high value resistors can be used to construct low
frequency filters. The AD862x’s picoamp-level input currents
contribute minimal dc errors. Figure 49 shows an example of a
10 Hz, 8-pole Sallen Key filter constructed using the AD862x.
Different numbers of the AD862x can be used depending on
the desired response, which is shown in Figure 48. The high
value used for R1 minimizes interaction with signal source
resistance. Pole placement in this version of the filter minimizes
the Q associated with the lower pole section of the filter. This
eliminates any peaking of the noise contribution of resistors in
the preceding sections, minimizing the inherent output voltage
noise of the filter.
