As said in datasheet, INA214-Q1 has fixed gain. But they choose large Rs, such as 10Kohm. So the calculated gain error would be very large, near to 90%. Then they use Gain_real= 100*(1-90%)= 10 as the real gain simply because they need a smaller gain. I know it's against what datasheet says and inappropriate but I cannot tell a solid reason. Could you please help explain what gain error means and why this method is not applicable? Thanks!
