INA214-Q1: INA214's gain error when Vsense is over 5mv

Part Number: INA214-Q1

Hi expert,

I wonder how to get gain error data over the test condition of datasheet shown below for INA214:

I searched through the datasheet and didn't get much that helps. For example, how do I know the Gain error when Vsense is from -20mV to 20mV?

Thanks

Sheldon

    Hello Sheldon,

    Gain error is consistent for different values of Vsense, as long as the device output is not saturated. We are not able to spec gain error at large Vsense values since we have some devices with gain as high as 500V/V or 1000V/V, which would saturate if we applied an input signal such as 20mV.
