INA240: Gain Error at Very Low Sense Voltage

Part Number:INA240

Hello,

I'm looking for a current sense amplifier that has very good linearity and gain error at low sense voltage (<10mV). I've found devices like the INA240 and LMP8480, but noticed that they don’t spec the gain error below 10mV sense voltage, or aren’t clear on the range for which the gain error spec is valid, respectively.

Could you help me narrow down which of the available devices will have the best linearity for applications with low sense voltages? We need a gain around 50V/V and common-mode range is never more than 55V.

Is there any test data for these low sense voltages?

Regards,
Ryan B.
