Teledyne e2v Strengthens Space-Grade ADC Offering with Radiation Robustness Results

GRENOBLE, France--(BUSINESS WIRE)--Teledyne e2v Semiconductors today announced new radiation test results for its EV10AS940, a 10-bit, 12.8 GSps, Ka-band-capable analog-to-digital converter, or ADC, developed for demanding space payloads and mission-critical applications.

These results give space engineers additional confidence when designing high-performance satellite communications payloads, synthetic aperture radar, or SAR, systems, space electronic intelligence platforms and advanced space instrumentation, where data-conversion speed, radiation tolerance and in-orbit reliability are critical to mission success.

As part of a comprehensive single event effects, or SEE, test campaign, multiple EV10AS940 samples were evaluated at leading radiation test facilities, including RADEF in Finland and the Texas A&M University Cyclotron Institute in the United States. The devices were exposed to heavy ions across a broad range of conditions, including linear energy transfer, or LET, values up to 94 MeV·cm²/mg.

Across all tested configurations, no single event latch-up, or SEL, events were observed, including at maximum LET levels, elevated temperature and increased supply-voltage conditions. At the conclusion of the campaign, all tested devices remained fully operational, with no functional degradation observed.

“These results give space system designers added confidence when selecting high-speed data converters for advanced payloads,” said Victoria Nasserddine, Product Marketing Manager at Teledyne e2v Semiconductors. “The EV10AS940 combines ultrahigh-speed performance with demonstrated radiation robustness, supporting applications where mission assurance and signal-chain performance are both critical.”

The EV10AS940 supports high-bandwidth applications that require fast, reliable conversion in harsh environments, including satellite communications, radar, electronic intelligence and advanced space instrumentation. The latest SEE results build on Teledyne e2v’s long-standing expertise in high-reliability semiconductor technologies for space and defense markets.

Total ionizing dose, or TID, characterization of the EV10AS940 has also been completed, confirming its robustness for long-term operation in radiation environments. Additional testing is ongoing, with complete reports expected by the end of 2026.
