Teledyne e2v Announces Radiation Test Results for EV10AS940 Space-Grade ADC

Teledyne e2v Semiconductors has released new radiation test results for its EV10AS940, a 10-bit, 12.8 GSps, Ka-band-capable analog-to-digital converter developed for space payloads and mission-critical applications.

The single event effects (SEE) test campaign evaluated multiple EV10AS940 samples at RADEF in Finland and the Texas A&M University Cyclotron Institute in the United States. Devices were tested with heavy ions across a range of conditions, reaching linear energy transfer (LET) values up to 94 MeV·cm²/mg.

No single event latch-up (SEL) events occurred in any tested configuration, including at maximum LET levels, elevated temperatures, and increased supply voltages. All tested devices remained fully operational with no functional degradation at the end of the campaign.

Total ionizing dose (TID) characterization of the EV10AS940 has also been completed. Additional testing is ongoing, with full reports expected by the end of 2026.

The EV10AS940 targets high-bandwidth applications including satellite communications, synthetic aperture radar (SAR) systems, space electronic intelligence platforms, and advanced space instrumentation.

“These results give space system designers added confidence when selecting high-speed data converters for advanced payloads,” said Victoria Nasserddine, product marketing manager ...
