The LMP2012QML-SP device is a dual high precision, rail-to-rail output operational amplifier with excellent CMRR and PSRR ratings, and does not exhibit the familiar 1/f voltage and current noise increases that plague traditional amplifiers. The QMLV version of the LMP2012 has been rated to tolerate a total dose level of 50-krad(Si) radiation by Ionizing radiation (Total Dose) test method 1019.4 of MIL-STD-883.
General device information and testing conditions are listed in Table 1-1.

Devices were exposed via fast neutron irradiation (FNI) at the University of Massachusetts Lowell Research Reactor (UMLRR). The facility is designed to give a fast flux level ≥ 1011 n/cm2–s, with relatively low thermal fluence and gamma dose rates. Samples with a cross-sectional area as large as 30 cm (12 in) × 30 cm (12 in) and up to 15-cm (6-in) thick can be irradiated. The fast neutron flux is designed to be nearly uniform over the 30-cm (12-in) × 30-cm (12-in) area facing the core, and the fast fluence variation through the sample thickness is minimized via a single 180° rotation of the sample canister at the midpoint of the irradiation period. The FNI facility offers a significantly larger sample volume than previously available within the University of Massachusetts Lowell Research Reactor (UMLRR).
The fluences are calculated based on 1-MeV equivalences.

There were no functional failures at any irradiation level. All parametric measurements remained well within all LMP2012QML Dual High Precision, Rail-to-Rail Output Operational Amplifier data sheet limits for all exposure levels. All parametric measurements remained well within the production test limits which are guard-banded from the data sheet limits. The full parameter list and graphs are found in Section A.
