MIL-M-38510-140 Microcircuits, Linear, Monolithic And Hybrid Silicon, Microprocessor Compatible, 12 Bit Analog-To-Digital ConvertersThis specification covers the detail requirements for monolithic and hybrid, microprocessor compatible, 12-bit successive approximation analog-to-digital converters buffered outputs. 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.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 end-point linearity error,

LE(N) = (E(N+766)+E(N+767)) / 2-V(ideal)) / S V(ideal) = N1* S+E767-S/2

N1 = Applied ref DAC code-word

S = (E760-E761) / 4094

Determine the code-word and the value of the maximum positive Linearity Error for all combinations of the digital input code words from (0000 0000 0000) to

(1111 1111 1111).
