SLAK033 December 2024 DAC121S101-SEP
The purpose of this study is to characterize the effects of heavy-ion irradiation on the single-event latch-up (SEL) performance of the DAC121S101-SEP, a single channel, 12-bit digital-to-analog converter (DAC). Heavy-ions with an LETEFF of 43 MeV-cm2/mg were used to irradiate two production devices with a fluence of 1× 107 ions/cm2 and one production device with a fluence of 1.5 × 107 ions/cm2. The results demonstrate that the DAC121S101-SEP is SEL-free up to LETEFF = 43 MeV-cm2/mg at 125°C.
