WebThe Sallen-Key low pass filter consists of an active component—an op-amp—as well as passive components such as resistors and capacitors. RC components control the frequency response characteristics, whereas the op-amp is responsible for the voltage amplification and gain control. The figure above shows a Sallen-Key low pass filter. WebA commonly available operational amplifier such as the uA741 has a typical “open-loop” (without any feedback) DC voltage gain of about 100dB maximum reducing at a roll off rate of -20dB/Decade (-6db/Octave) as the input frequency increases.
