The DAC121S101-SEP is a radiation-hardened device in a plastic package that allows these devices to be used in space applications. The device was verified immune to 43 MeV × cm²/mg at 125°C for single-event latch-up (SEL). Each fabrication lot was tested according to MIL-STD-883 for radiation lot acceptance tested (RLAT) up to 30 krad(Si) and each assembly and test lot follows the process flow shown in Figure 2-1. To verify the quality of the DAC121S101-SEP, the device is qualified with SEP requirements. For more details, see Section 3.
