Hi,
My customer is wondering how to design the input filter, can you help to give us some comment?
How to calculate the filter resister and capacitor.
Great thanks for your help.

Hello user,
Please see the diagram below from the INA190 datasheet. The equation for setting the differential-mode input cutoff frequency is given. I suggest picking your -3dB frequency, picking your resistor value (should be < 100 ohms), then solving for C.
