Multiple Devices on One Bus(AD5173 Only)

Figure 54 shows four AD5173s 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.
