8.2.1.2 Detailed Design Procedures

Connect the output of one INA28x-Q1 family device to the reference input of the next INA28x-Q1 family device in the chain. Use the reference input of the first circuit to set the reference of the final summed output. The currents sensed at each circuit in the chain are summed at the output of the last device in the chain.
