Multiple Devices on One Bus

Figure 47 shows four AD5170s 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.
