Automotive Signal Processing

Designing the car of the Future with Today's Signal Processing ICs from ADI

As automobiles become more complex, the use of signal processing technologies is rapidly increasing. In fact, analysts predict electronics will constitute 40% of a vehicle's manufacturing cost by 2010, up from nearly 25% today.

Analog Devices is ahead of the curve with more than 40 years of functional signal processing experience acquired in a variety of performance driven markets. What's more, our total quality philosophy emphasizes prevention rather than detection and reflects our commitment to continuous improvement of world class systems and processes. All ADI plants are ISO 9001, ISO 2000, QS-9000, ISO 14000, and ISO/TS 16949 certified. Our focus on technology, quality, reliability, service, and cost is aimed at satisfying the evolving requirements of automotive system designers who are meeting modern demands for safety, efficiency, performance, and a greater variety of entertainment options.

For example, Analog Devices is addressing the special requirements of hybrid vehicles by offering the first digital isolator to carry a –40°C to +125°C AEC-Q100-qualified automotive temperature rating for hybrid electric systems. Smooth transitions between power sources in hybrid vehicles are accomplished using ADI resolver-to-digital converters. In addition, ADI has the battery and power monitoring ICs optimized for the new class of Li-Ion hybrid vehicles, known as plug-ins. These vehicles promise to deliver fuel ratings in excess of 100 miles per gallon.

Smarter airbag systems—capable of identifying different crash types—are critical for improved passenger safety. ADI enables these systems with the industry's only dual spectrum MEMS accelerometer for airbag deployment. It features a vibration detection path to complement the conventional inertial sensing path for more precise airbag deployment across a wide range of crash scenarios.

Audi® has selected Blackfin® and SHARC® processors for the A5 coupe's entertainment systems. Now, the same ADI processors that provide reliable digital signal processing for home entertainment systems are the foundation for Audi's in-vehicle audio subsystems. ADI also offers a powerful family of digital audio processors and design tools to provide a seamless environment for designers to create multichannel digital audio platforms and simplify driver interfaces.

The car of the future will have a nervous system of semiconductor sensors, logic, and signal conditioning to make it more acutely aware of its environment. As the demand for economy, performance, safety, and reliability push engineers toward lighter and smarter designs, the role of Analog Devices' signal processing technologies will continue to grow.
