Dear, Sir.

INA193A-Q1 datasheet difines ;

Vos(RTI), Total output error with remarks (1).

The remarks is explaning "the error includes the effects gain error & Vos".

I would like to double-confirm it is really no problem such like +-3%(full range) should be includes Vos because

Vos affects huge on the error.

Please give your advice.

Best Regards,

Hi Sakay,

Thank you for using TI E2E forums.

I can confirm the error includes both the effects gain error & Vos, as per datasheet.

Hi Sakay,

In addition to my last post I think it is appropriate to remind the accuracy variations based on input level, as defined in the device datasheet, which can be found at www.ti.com/.../ina193a-q1.pdf.

To obtain the accuracy mentioned in the datasheet, Vsense must fall within 20 and 100mV, as per section 7.4.2, which I recommend reviewing.
