SBAK020 April 2025 ADC3683-SEP
PRODUCTION DATA
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 Silver (109Ag) ion with an angle-of-incidence of 0° for an LETEFF = 51.12MeV × cm2/ mgm. Flux of 105 ions / cm2× s and a fluence of 107 ions / cm2 were used. 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-SEP is SEL-free. Table 7-2 lists the SEL test conditions and results. Figure 6-1 shows a typical plot of current versus time for SEL testing.
| Run Number | Temperature | LETEFF (MeV × cm2/mg) | Flux (ions × cm2/s) | Fluence (ions × cm2) | AVDD/IOVDD (V) |
|---|---|---|---|---|---|
| 1 | Room, approximately 25°C | 51.12 | 1.85 × 104 | 1 × 107 | 1.9 |
| 2 | 125°C | 51.12 | 1.8 × 104 | 1 × 107 | 1.9 |
| 3 | 125°C | 51.12 | 1 × 105 | 1 × 107 | 1.9 |
| 4 | 125°C | 51.12 | 1 × 105 | 1 × 107 | 1.9 |
