Note that the specified accuracy of the INA26, INA207, and INA208 must then be combined in addition to these

tolerances. While this discussion treated accuracy worst-case conditions by combining the extremes of the

resistor values, it is appropriate to use geometric mean or root sum square calculations to total the effects of

accuracy variations.
