Content	Energy Efficiency ADI helps technology consumers save money and energy, and reduce their climate change impact, by developing low-power-usage electronic devices for a multitude of products. We have been the leader for years in defining and pushing the power/performance boundary. With digital and analog technologies generally, more power is typically required to achieve higher accuracy, more bandwidth, and greater precision. Our focus on innovation has resulted in products that use less power than our competition while still meeting the increased performance requirements of customers’ next-generation systems. Examples1 include the following: • In 2006, we expanded our PulSAR® family of analog-to-digital convert- ers, which are used in wearable medical electronics such as EKG and blood pressure monitors. The latest PulSAR converters use 80% less power than competing analog-to-digital converters. • In 2006, we advanced our leadership in energy-efficient precision amplifiers by introducing the AD8500, which uses 30% less power than alternative products but delivers superior performance, thus extending the battery life of precision sensing equipment such as smoke detectors and glucose monitors. • In 2008, we continued to define and push the power/performance boundary, improving the energy economy of our leading-edge TxDAC® family of digital-to-analog converters by introducing devices that use 40% to 70% less power than competing products. These converters reduce the energy required for cellular infrastructure miniature base stations. 1The comparative claims in these examples were calculated at the time the products were introduced. Our products are also used in applications that generate energy and monitor and regulate energy use. Examples1 include the following: • In May 2008, we extended the reach of our iCoupler® data and power isolator product family, which addresses the isolated commu- nication needs in a variety of advanced power generation systems. For example, these products are now used in a residential solar power system that generates power 25% more efficiently than alternative approaches. • In February 2008, we introduced the ADP1043, a digitally controlled power management system integrated circuit that is used in commu- nications infrastructure to convert line power to system power more efficiently than alternative approaches. Our product reduces by 10% the power loss seen in standard systems. • In March 2008, we launched the ADM1184, a power monitoring integrated circuit used in applications including Ethernet routers, data storage, and data centers. Accurate power monitoring enables system controllers to reallocate work to shut down unneeded computing blocks and save power. Materials Use ADI designs products that make efficient use of materials, and we use substitutes for materials that are restricted in parts of the world. During the last several years, we have focused on designing products that conform to the European Union’s Restriction of Hazardous Substances (RoHS) product content directive. The RoHS directive, which took effect in 2006, restricts the presence of several substances used in electronic products, including mercury, lead, cadmium, hexavalent chromium, and two flame retardants. We provide customers and poten- tial customers with a master listing of our products’ RoHS compatibility, so they can confirm that our products conform to this legislation. 40 Analog Devices Sustainability Report 2007 • Products Product Stewardship A significant amount of Analog Devices’ environmental impact stems from customers’ use of our products. We are committed to the principles of Design for Environment (DfE) and incorporate product stewardship principles into our product designs. Our areas of focus include energy efficiency and materials use.
