FILTERED_SAMPLE_AND_HOLD
It is often required that a signal be filtered pnor to sampling. This can be accomplished with only one device. Use any of the inverting and noninverting filters that can be built with op amps. However, it is necessary that the sampling switch be closed for a sufficient time for the filter to settle when active filter types are connected around the device.
