INA226 Q1 ADC offset current & INL

Hello,

Let me move this to the current sensing forum, they should be able to answer your question.

Hi na na78,

1. I am assuming you want the offset current reading from the ADC which will be the offset voltage spec multiplied by the calibration reg value.

2. The INL for the INA226 is in the order of a few LSB’s. We had characterized it but I am not able to find the data right now.

Hi Mayrim

Thank you for your reply.

1. Do you mean offset voltage multiplied by the CAL is offset current?

2. Can you find INL value?

We appreciate to your support.

Hi Mayrim

Thank you for your answer.

I'msorry, but could you please review if following example is correct?

If CAL = 2048 and offset voltage is 2.5uV (from datasheet), then offset current = 5.12mA.

Hi Mayrim

Sorry for bothering you.
We thank for your comment for last question.

Hi na na78,

Your example is correct!
