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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3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 = 410((Vm(N) - Vm(N-1))/G1H  - 10/4096) Where Vm = measured value V55  through V78

" N = N + 1" are the decimal equivalents of

the code words in column "7 thru 18"

Example: For the first set

N = 1000 0000 0000 = 211  = 2048

N - 1 = 0111 1111 1111 = 211  - 1 = 2047

and Vm(N) = V56

Vm(N-1) = V55
