ADI has a team dedicated to supporting aviation development and production in the broad global market, and continues to expand the applicability of products to support the rapidly growing market. In addition, ADI has expertise in building and supporting customers in the avionics and unmanned systems markets.

The main challenges in aerospace design are -

• RTCA（ Radio Technical Commission for Aeronautics ) considerations and DO 178B/C, DO 160 and DO 254 functional safety certification requirements. These requirements are extremely stringent and detailed, requiring careful consideration of the design and the components included therein.

  
  

  Many of the issues revolve around complex components, redundant paths and known failure modes. Certification requirements are becoming increasingly complex based on the impact on flight safety.

• The aviation industry is replacing pneumatic and hydraulic devices with electronic systems. Components and assemblies are exposed to harsher environmental conditions in terms of temperature, corrosiveness, etc.

ADI supports many of its large aerospace customers with the documentation required for DO 178/DO 254 certification. Equally important, ADI has processes and catalogs for high-performance devices for the aerospace industry that feature nickel-palladium-gold leadframes (to reduce tin whisker effects) and specialized non-copper internal wire bonds (to resist corrosion) and operate over a –55°C to +125°C temperature range (some up to +175°C).

Currently, ADI has more than 100 enhanced product (EP) products and more than 600 devices with NiPdAu leadframe in the catalog. ADI continues to introduce new EP devices to support the commercial aviation market. In the future, ADI will continue to transform traditional devices into practical EP devices.

• The product is rated for temperatures ranging from –55 to +125°C;

• The default pin surface treatment is NiPdAu, and some packages use SnPb;

• EP devices will have separate data sheets;

• The tightly controlled production facility includes an assembly plant, a testing plant, and a manufacturing plant.
