LTC1857: Has anyone used the MUXOUT+, MUXOUT- with a cap as the anti aliasing filter?

Question

The LTC1857 allows the 8 input mux signals connect to external pins. A connection to the A/D is on two other pins. It is possible to place a small cap for filtering at this point? I didn't find any data on how to use these pins. This would be nice to use as one LPF instead of eight.

RC filters can be placed between Muxout+ and ADCin+ and between Muxout- and ADCin- to provide filtering. This reduces the number of filters required from eight to two. You must make sure that the filter completely settles between conversions so that crosstalk between the channels does not occur.
