9.1.2 Connecting Multiple Devices on the Same I²C Bus

Up to 16 ADS1119 devices can be connected to a single I²C bus by using different address pin configurations for each device. Use the address pins, A0 and A1, to set the ADS1119 to one of 16 different I²C addresses. Figure 44 shows an example with three ADS1119 devices on the same I²C bus. One set of pullup resistors is required per bus line. If needed, decrease the pullup resistor values to compensate for the additional bus capacitance presented by multiple devices and increased line length.
