... AD825, one needs to consider the input capacitance ( pF) of the AD825 as part of the passive network. GROUNDING AND BYPASSING The AD825 is a low input bias current FET amplifier. Its high frequency response makes it useful in applications, such as photodiode interfaces, filters, and audio circuits. When designing high frequency circuits, some special precautions are in order ...

... SECOND-ORDER LOW-PASS FILTER 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 ...
