8.2.1 Current Summing

The outputs of multiple INA28x-Q1 family devices are easily summed by connecting the output of one INA28x-Q1 family device to the reference input of a second INA28x-Q1 family device. The circuit configuration shown in GUID-F026D8A4-47FB-4BAF-9495-89BCBBD04A01.html#SBOS4859865 is an easy way to achieve current summing.

NOTE: The voltage applied to the reference inputs must not exceed 9 V.
