Hello,
I would just have them confirm that they understand the gain error factor as a result of the input filter.
I would also make sure that they understand that the voltage divider on the reference is the lowest cost solution, however a buffer on this divider or a reference IC would improve the accuracy.
What kind of ADC is the output of the INA199 driving?
Please also take a look at Current Shunt Amplifier Considerations for Driving SAR ADCs if the output of the INA199 is driving a SAR ADC, I would recommend using a charge bucket filter like below:
Other than the above, I think the schematic looks good.
Best Regards,
Joe
