It is possible to connect up to four ADS101x-Q1 devices to a single I2C bus using different address pin configurations for each device. Use the address pin to set the ADS101x-Q1 to one of four different I2C addresses. Use the GND, VDD and SCL addresses first. If SDA is used as the device address, hold the SDA line low for at least 100 ns after the SCL line goes low to make sure the device decodes the address correctly during I2C communication. An example showing four ADS101x-Q1 devices on the same I2C bus is shown in Figure 27. One set of pullup resistors is required per bus. The pullup resistor values may need to be lowered to compensate for the additional bus capacitance presented by multiple devices and increased line length.
