More on Crosspoints.

   The MAX335 looks like an excellent chip for your application, Paul!

   More thoughts on the subject, regarding Crosspoint chips...

   Having looked at the Mitel chip MT8816, I noticed that you can 
literally control each switch.  Well, wouldn't it work that if you tie 
the output lines directly to an opamp's in I/V configuration and then put 
the input resistor on the input line of the crosspoint...would that work 
then?  You wouldn't get any additional feedback from one channel to the 
next because the inputs are now protected.  The output is your summing 
node of your op-amp which should now handle the multiple signals being 
fed by the multiple switch-points.
   I suppose the issue then is if the crosspoint is feeding current, if 
so, then perhaps this would be a single chip solution!
   Feedback?  I'm probably way off.  :)

   Tony
