Why Choose ADI

ADI has a dedicated team supporting aviation development and production across a wide range of global markets, continually expanding the applicability of its products to meet the demands of fast-growing markets. Additionally, ADI excels in building and supporting customers' avionics and unmanned systems markets.

Key Challenges and System Design Considerations

The primary challenge in aerospace design lies in adhering to RTCA (Aeronautical Radio Technical Committee) considerations and meeting rigorous DO 178B/C, DO 160, and DO 254 functional safety certification requirements. These standards are incredibly stringent and demand meticulous attention to detail in both the design and the components selected.

Many issues revolve around complex components, redundant pathways, and known failure modes. As certification requirements become more intricate due to their impact on flight safety, the complexity of these designs increases accordingly.

The aviation industry is increasingly relying on electronic systems to replace traditional pneumatic and hydraulic components. This shift subjects components to harsher environmental conditions, including extreme temperatures and corrosive environments.

ADI supports numerous major aerospace customers and provides the necessary documentation for DO 178/DO 254 certifications. Equally important, ADI offers high-performance device processes and catalogs specifically designed for the aerospace industry, featuring nickel-palladium-gold leadframes (to mitigate tin whisker effects) and special non-copper internal wire bonds (for corrosion resistance), with operating temperature ranges from -55°C to +125°C (and some up to +175°C).

Commercial Aviation Signal Chain

Enhanced Products

Currently, ADI’s catalog includes over 100 enhanced product (EP) items and more than 600 devices utilizing nickel-palladium-gold lead structures. Analog Devices continues to introduce new EP devices to support the commercial aviation market, and in the future, they will continue to convert traditional devices into practical EP devices.

The products are rated for temperatures ranging from -55°C to +125°C;

Surface treatment of pins defaults to NiPdAu, with some packages using SnPb;

EP devices will have separate data sheets;

Strictly controlled production facilities include assembly plants, test plants, and manufacturing plants.
