+#### Multiple ADG725 in parallel
+
+**To be tested**
+
+It seems possible to connect multiple ADG725 devices side by side and control 
+them as one. This would allow to create e.g a fast 8x16 multiplexer.
+
+If you want to control them separately, every device need its own **syncPin**
+a.k.a. Chip Select Pin. The data- and clockPin can be shared.
+If you want to control them as one, all three lines should be shared.
