INA139: Total output error

Kei Kuwahara

Part Number: INA139

Hello team,

I want to clearify the terms in datasheet.

In the datasheet, the total output error is +/- 2% (max).
What is total output error mean? Is this output current error, including all the offsets, gain errors, etc?

Best Regards,
Kei Kuwahara

Kei,

Thanks for the question and using the E2E forum.

We're looking into this and will give you an update when we return from the holiday week.

Correct; this includes the effects of all possible errors.

For example, if the theoretical output current would be expected to be 100 µA, the actual worst-case output current could be between 98 µA and 102 µA.
