Multiple Devices on One Bus (Applies Only to AD5248)
Figure 49 shows four AD5248 devices on the same serial bus.
Each has a different slave address because the states of their
AD0 and AD1 pins are different. This allows each device on the
bus to be written to or read from independently. The master
device output bus line drivers are open-drain pull-downs in a
fully I2C-compatible interface.
