Analog technologies, also known as linear technologies, are the essential link between the digital world of ones and zeroes and the real world of light, sound, temperature, speed, and pressure. National’s technologies address issues facing system designers in markets such as mobile handsets, communications and industrial applications. Proven Analog Technology Leadership National’s analog portfolio features leading-edge operational amplifiers, interface technologies, data converters, and power management solutions. These devices provide solutions for high-efficiency lighting, precision data acquisition, high-speed serial communication and power conversion. As a recognized world leader in power management, National continues to pioneer new energy-efficient devices, sub-systems and architectures for next-generation system designs. PowerWise® Products for Energy-Efficient Designs Energy conservation is important all over the world, and National’s rich portfolio of energy-efficient integrated circuits (ICs), reference designs and design tools help designers create electronic systems that consume less power. National’s PowerWise® portfolio designates the company’s most energy-efficient products, featuring more than 300 devices with outstanding performance-to-power ratios. Metrics for PowerWise devices provide an energy-efficiency rating, making it easy for system designers to identify the most energy-efficient devices for their end products. PowerWise Adaptive Voltage Scaling Technology National’s PowerWise Adaptive Voltage Scaling (AVS) technology enables longer battery life, more features, and improved user experience by reducing the energy consumption in digital processors by up to 70%. 美国国家半导体致力于开发各种高能源效率的模拟及混合信号半导体产品。采用该公司 PowerWise®产品的系统可以减少功耗，延长电池寿命，以及耗散更少热能。美国国家半导体总公司设于美国加州圣塔克拉拉 (Santa Clara)，截至2008年5月25日为止的2008 年财政年度的营业额达18.9亿美元。
