SBAK019 May 2024 ADC3683-SP
During SEL characterization, the device was heated using forced hot air, maintaining the DUT temperature at 125°C. The die temperature was monitored prior to radiation using a FLIR IR-camera.
The species used for the SEL testing was Praseodymium (141Pr) ion with an angle-of-incedence of 30° for an LETEFF = 79MeV×cm2/ mgm. Flux of 105 ions / cm2× s and a fluence of 107 ions/cm2 were used for the three runs. Run duration to achieve this fluence was less than two minutes. The device was powered up and exposed to the heavy-ions using voltages up to 1.9V, with 1.85V being the maximum recommended operating voltage. No SEL events were observed during all three runs, indicating that the ADC3683-SP is SEL-free. Table 7-1 shows the SEL test conditions and results. Figure 7-1 shows a typical plot of current versus time for an SEL testing.
