The DAC39RF10-SP HDR exposure was performed on biased devices in a Co-60 gamma cell at TI's CLAB facility in Dallas, TX. The unattenuated dose rate of this cell is 120 rad(Si)/s. After exposure, the devices completed a full post irradiation electrical evaluation using the production test, or ATE, solution. ATE guard banded test limits are set within data sheet electrical specifications to ensure a minimum Cpk and test error margin based on initial qualification and characterization data. Post-irradiation measurements were taken within 30 minutes of irradiation.
