Heavy Ion Single Event Effects (SEE) results for OPA128 Electrometer Grade Operational Amplifier
The OPA128 is an electrometer grade operational amplifier with femtoamp bias currents [1], potentially offering better performance than other rad-hard precision op amps available today [2], [3], [4], [5], [6]. Heavy ion testing to qualify it for use on the Europa Clipper mission uncovered a destructive failure not noted in prior testing [7], [8], [9], precipitating additional testing to explore the failure and determine the part's viability for spaceflight. Testing yielded a proposed safe operating area (SOA). Non-destructive transient events were also observed and characterized for multiple applications.
