INA212: offset voltage spec referred-to-input

Mia Ma

Part Number: INA212

Hi team,

About our INA212 offset voltage spec as following:

What does the 'RTI' mean? Does this mean the offset error should be calcualted into input side; and the output side offset error will be the Vos*Gain like normal amps?

If any understanding is wrong, pls help to clarify it.

Thanks

Best regards

Yes.

Mia,

As Kai said, your understanding is correct. RTI (referred-to-input) means the offset error is added onto the input voltage and when it appears at the output it will be amplified by the gain.
