Lowpass filter.

The 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.
