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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3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((E119-E120)(N/4095) + E120  -EA) Where

EA = measured value E185  through E4280

N = DUT 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.

E119  and E120  correspond to the error amplifier Outputs at full scale and zero scale Respectively.

Worst positive error Worst positive code Worst negative error Worst negative code
