Hi All
I need to understand the error caused by putting external resistors in series with the inputs a bit more. If I am to apply gain error equation given in the datasheet, with 1000 Ohms external resistors, then the equation tells me that I would incur a gain error of 25% based on the calculated gain error factor of 75. Does this mean that my error as an example for the INA240A1 instead of the specified 20V/V +/- 0.2% maximum would be 20V/V +/- 25%? How is the "Gain Error Factor " derived and how does the "Input Bias Current vs Differential Input Voltage" plot fit in all of this?
