INA293: Accuracy variations

Part Number: INA293
Other Parts Discussed in Thread: INA193, INA271,


Could you please share the detailed information with me if the output voltage accuracy is affected by Vsense and Vcm such as INA193?

Best regards,

  • Sadanori-san,

    The above cases are for a specific architecture of older device, of which INA293 is not a part of (these devices are INA193, INA271, etc.). See the below snippet from section 7.4.1 of the INA293 datasheet:

    Provided the input to the device produces at least 20mV on the output of the device, it will operate in the linear range, provided the device is within the common mode range. Also keep in mind this is the worst case condition, and performance will typically be better than this. 

  • Hi Carolus-san,

    Thank you for the information.

    I understand.

    Best regards,
