MIL-M-38510-121 Microcircuits, Linear Monolithic And Multichip, Silicon 12 Bit Digital-To-Analog ConvertersThis specification covers the detail requirements for monolithic silicon, bipolar, interface, memory core drivers. Two product assurance classes and a choice of case outlines and lead finishes are provided and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3

For each set of major carry codes N and N + 1

Calculate the associated error in LSB's as

Follows:

MCE = 4.1 (EA - EB)

where

EB = measured value from E40,E42,E44,etc. EA = measured value from E41,E43,E45,etc.
