DC ERROR

Question

Hello I want to calculate output voltage offset of ADA4941-1. In the Datasheet, the "DC ERROR CALCULATONS" part seems to be similar to output voltage offset , is this right to mean output voltage offset? VO_error, dm = VOP_error - VON_error Is this equation the output voltage offset? And please let me know exactly what VOS_nom means and tell me the difference between VO_error, dm and VOS_nom. 
 thank you.

Hi ssuihee, Vo_error is the differential offset voltage taken between pins 4 and 5. 
 Vo_error was then changed to Vos_nom on equation 12. These are just the total voltage offsets due to per amplifier Vos, Ios and gain and feedback resistors. 
 Equation 12 includes all the parameters that can affect the total Vos of the part.
