INA296B-Q1: RVRR (Reference voltage rejection ratio) specification

TI Team,

Cusotmer calculates worst case error for INA296B-Q1 output. 

In the datasheet a RVRR (Reference voltage rejection ratio, input referred) parameter is specified for the case when Vref1 = Vref2 = Vs / 2. In customer application Vref1 = GND, Vref2 = Vs(5V).

How should we evaluate the RVRR error in this case?

    Hello Piotr,

    When using the internal resistor divider please use the Reference divider accuracy for you gain options.  For your device INA296B please use the 0.15% resistor divider error.  This is the error for the reference and this should not change during operation.  So the RVRR does not apply.

    Regards,
