For each input code N calculate the corresponding linearity error in LS8. LE = ((EA/G1)+(N)(K)-(VOS))/(9.7656E-3) where EA = measured value E103 through E123 G1 = error amplifier gain from step 111 N = DUT input digital code word in decimal form. Thus for 10 bits N = (A1)(2exp7)+(A2)(2exp6)+… +(A10)(2exp0) A1,A2, … A10 are 0 or 1. K = actual volts/count scale factor. K = (VFS - VOS)/1023 where VFS = Value at E89 VOS = Value at E90 |

For each set of major carry codes N and N+1 calculate the associated error in LS8's as follows: MCE = ((E8-EA)/G1)(9.7656E-3) where E8 = Measured value from E124, E126, E128, etc. EA = Measured value from E125, E127, E129, etc. |
