Hello，

Good day.

The offset voltage of the ina186 is 50uV at a gain of 25. will there be a deviation of 1.25mV at the output port?

The offset voltage is referred to the input. So at the output, the offset will be 25 times higher.

Hi Clemens,

Thank you for jumping in, as usual :)

Hi Yuhao,

Thank you for your post. Clemens is absolutely correct. The input offset will be gained by 25.

I hope this makes sense.

Best Regards,

Joe
