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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3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 input code N calculate the

Corresponding linearity error in LSB.

LE = 4.1((E65-E66)(N/4095) + E66  -EA)

where

EA = measured value E70  through E92

N = OUT input digital code word in decimal form

Thus for 12 bits N = (A1)(2 exp 11) + (A2) (2 exp 10 )+ … +(A12)(2 exp 0)

A1, A2, A12 are 0 or 1.

E65  and E66  correspond to the error amplifier Outputs at full scale and zero scale respectively.
