Consider the ADR421ADR421. From the data sheet the initial accuracy is shown to be + or - 3mV of the nominal (2.5V). I understand that if you power on one of these chips with conditions at 25 degrees C, Vin = 5-15V, you will expect output in that initial accuracy range.. But does this mean that the output voltage is expected to change from + or - 3mV if kept at those same conditions?

I know that there are things like long term stability and thermal hysterisis but i'm asking strictly about the initial accuracy.

Does initial accuracy tell us anything about output voltage drift with reference voltages?
