SBOK070 November 2022 OPA4H199-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 OPA4H199-SEP, quad-channel 40-V, 4.5-MHz, rail-to-rail input and output (RRIO) operational amplifier. Heavy-ions with an LETEFF of 43 MeV-cm2/mg were used to irradiate the devices with a fluence of 1 × 107 ions/cm2. The results demonstrate that the OPA4H199-SEP is SEL-free up to LETEFF = 43 MeV-cm2/mg at 125°C.
