Multiple Devices on One Bus
Figure 47 shows two AD5245 devices on the same serial bus.
Each has a different slave address because the states of their
AD0 pins are different. This allows the RDAC within each
device to be written to or read from independently. The master
device’s output bus line drivers are open-drain pull-downs in a
fully I

C-compatible interface.
