AD704
The 1 Hz, four-pole active filter offers dc precision with a
minimum of components and cost. The low current noise,
I
the 1 μV/°C drift of the AD704. This means that lower capacitor
values can be used, reducing cost and space. Furthermore,
because the AD704’s I
temperature range, most applications do not require the use of
the normal balancing resistor (with its stability capacitor).
Adding the optional balancing resistor enhances performance at
high temperatures, as shown in Figure 36. Table 5 gives
capacitor values for several common low pass responses.

Specified values are for a −3 dB point of 1.0 Hz. For other frequencies, simply scale the C1 through C4 capacitors directly; that is, for a 3 Hz Bessel response,
C1 = 0.0387 μF, C2 = 0.0357 μF, C3 = 0.0533 μF, and C4 = 0.0205 μF.
