General Configurations

When receiving low-level signals, limiting the bandwidth of the incoming signals into theFigure 50 system is often

required. The simplest way to accomplish this is to place an RC filter at the noninverting terminal of the amplifier

(see ).

Figure 50. Single-Pole Low-Pass Filter

If even more attenuation is needed, a multiple pole filter is required. The Sallen-Key filter can be used for this

task. For best results, the amplifier should have a bandwidth that is 8 to 10 times the filter frequency bandwidth.

Failure to do this can result in phase shift of the amplifier.
