MULTIPLE DEVICES ON ONE BUS
Figure 20 shows four ADG728s devices on the same serial bus.
Each has a different slave address since the state of their A0 and
A1 pins is different. This allows each Matrix Switch to be writ-
ten to or read from independently. Because the ADG729 has a
different address to the ADG728, it would be possible for four
of each of these devices to be connected to the same bus.
