calculate gain error drift

Hello,

 

I have some trouble with the calculation of the gain error drift by the AD7903.

 

gain error = +-0,04%FS

gain error drift = 0,19ppm/C

 

My reference voltage is 5V.

gain error = +-0,04%*5V / 100% = +-2mV

gain error drift = +-2mV/1e6 * 0,19/C = +-380pV/C

 

Im not sure, if I should taken 2mV or 5V by the calculation of the gain error drift.

 

Best regards,

 

Dirk
