Also, ADI has expertise in building and supporting customers' avionics and unmanned systems markets.

Key challenges and system design considerations

The main challenge in aerospace design is -

RTCA ( Aeronautical Radio Technical Committee ) considerations and DO 178B/C, DO 160 and DO 254 functional safety certification requirements. These requirements are extremely rigorous and detailed, requiring careful consideration of the design and the components it contains.

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

The aviation industry is using electronic systems to replace pneumatic and hydraulic components. In terms of temperature, corrosivity, etc., components and components are subjected to harsher environmental conditions.

ADI supports many major aerospace customers and provides the documentation required for DO 178/DO 254 certification. Equally important, ADI has high-performance device processes and catalogs for the aerospace industry that use nickel-palladium-gold leadframes (to reduce tin whisker effects) and special non-copper internal wire bonds (corrosion-resistant) for operating temperature ranges. It is –55°C to +125°C (partially up to +175°C).

Commercial aviation signal chain

Enhanced product

Currently, there are more than 100 enhanced product (EP) products and more than 600 devices using nickel-palladium-gold lead structures in the ADI catalog . Analog Devices 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 from –55 to +125 °C;

Pin surface treatment defaults to NiPdAu, and some packages use SnPb;

EP devices will have separate data sheets;

The strictly controlled production facilities include an assembly plant, a test plant and a manufacturing plant.
