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

Key Terms

analog-to-digital converter technical

An analog-to-digital converter turns continuous real-world signals—like sound, light, temperature or voltage—into a stream of numbers a computer can read, similar to translating a spoken sentence into typed text. Investors care because this tiny component determines how accurately and quickly devices sense the world, affecting product performance, battery life and manufacturing cost; its quality and cost can influence competitiveness and market demand across many electronics-driven industries.

ka-band technical

Ka-band is a slice of the microwave radio spectrum (roughly 26.5–40 GHz) commonly used for satellite links and high-capacity wireless backhaul. Because it carries more data per second and lets antennas be smaller, it can enable faster internet and more channels, but its higher frequency is also more prone to signal loss in heavy rain or obstacles. Investors track Ka-band deployment and equipment costs because it affects a company’s ability to deliver high-speed services, coverage economics, and revenue potential.

single event effects technical

Single event effects are malfunctions in electronic chips or circuits triggered by a single energetic particle (for example a cosmic ray or radiation) that can cause a temporary glitch, a flipped bit, or permanent damage. For investors, they matter because they affect product reliability, warranty and repair costs, regulatory approvals and customer trust—like a small stone suddenly cracking a car’s sensor—so companies’ testing, design fixes and supply choices can change future earnings and risk.

single event latch-up technical

Single event latch-up is a failure mode in electronic chips where a single energetic particle (from cosmic rays or radiation) triggers an internal short circuit that lets current run away until the device shuts down or is damaged. For investors, it matters because latch-up can cause sudden product failures, costly repairs or replacements, and higher warranty or reliability risks for companies producing or using electronics in high-radiation environments like satellites, aviation, or nuclear applications.

linear energy transfer technical

Linear energy transfer (LET) measures how much energy ionizing radiation deposits as it travels through tissue, expressed per unit distance along its path. It matters to investors because higher-LET radiation causes denser, more damaging cellular injury and can influence the effectiveness, safety, dosing and regulatory review of radiotherapies and radiopharmaceuticals — think of a single heavy ball making a deep dent versus many light pebbles leaving shallow marks.

total ionizing dose technical

Total ionizing dose (TID) is the cumulative amount of ionizing radiation energy absorbed by a material or electronic component over time. Investors should care because TID measures long‑term wear from radiation—like how prolonged sun exposure fades fabric—so it affects product reliability, compliance testing, warranty costs and marketability for devices used in medical, aerospace, defense and industrial environments.

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.

EV10AS940 10-bit, 12.8 GSps space-grade analog-to-digital converter from Teledyne e2v Semiconductors.

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.
