Analog Devices Introduces Industry's First Single- Package Solution for Data and Power Isolation.NORWOOD, Mass. -- ADI extends iCoupler(R) family of digital isolators with a complete solution that dramatically reduces board space and cost for industrial, instrumentation and power applications. Analog Devices Analog Devices (NYSE: ADI) is an American multinational producer of semiconductor devices. Analog specializes in ADC, DAC, MEMS, and DSP chips for consumer and industrial goods. Analog is presently designing circuits in the 65 nanometer to 3 µm process feature sizes range. , Inc. (NYSE NYSE See: New York Stock Exchange : ADI), a global leader in high-performance semiconductors for signal processing See DSP. applications, is extending its industry-leading family of iCoupler(R) digital isolators with the industry's first products that provide both data and power isolation in a single package. Unlike existing solutions that require the configuration of separate signal and power circuitry involving multiple components, this advancement provides designers of industrial, instrumentation, and power systems with a simple, low-cost, space-saving alternative. The products incorporate ADI's new proprietary isoPower(TM) technology that integrates a micro-power supply with independent signal channels. This eliminates the need for complex, sizeable, and costly combinations of optocouplers, transformers and other components, thereby reducing cost by as much as 70 percent and board space by as much as 80 percent. Announced today, the ADuM5240, ADuM5241 and ADuM5242 are dual-channel isolators incorporating isoPower technology. These new products, provided in 8-lead SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. (small-outline integrated circuit A Small-Outline Integrated Circuit (SOIC) is an integrated circuit (IC) package which occupies an area about 30 - 50% less than an equivalent DIP, with a typical thickness that is 70% less. They are generally available in the same pinouts as their counterpart DIP ICs. ) packaging, integrate an isolated power supply with two digital signal channels to create a complete isolation solution for low-power applications found in factory automation equipment, instrumentation and secondary control power supplies. In such applications, where designers are under great pressure to reduce size, cost and development time, the ADuM524x product family simplifies the challenge of isolated designs with a single-component solution. As with all iCoupler products, these new devices will carry regulatory safety approvals from the major North American North American named after North America.

"ADI's iCoupler digital isolation products have a solid five-year track record of safe, reliable operation in a wide variety of applications. Since 2001 when we first introduced the breakthrough iCoupler products, which proved far superior to optocouplers, iCoupler usage has grown to more than 50 million isolation channels in the field," said Dick Meaney, vice president, precision signal processing group, Analog Devices. "We are now leveraging our iCoupler technology to solve a challenging problem: isolating power along with data in a small space at a low cost. Our new iCoupler products with isoPower capabilities enable customers to achieve these savings as well as reduce development time." About the ADuM524x iCoupler Digital Isolators with isoPower Technology The ADuM524x products incorporate the isoPower technology, which integrates an isolated DC/DC converter (1) A device that changes one set of codes, modes, sequences or frequencies to a different set. See A/D converter. (2) A device that changes current from 60Hz to 50Hz and vice versa. with two channels of digital signal isolation in an 8-lead SOIC. Intended for low-power applications, the integrated DC/DC converter provides up to 50 mW of isolated, regulated power at 5 V. The ADuM524x devices operate with a supply voltage ranging from 2.7 V to 5.5 V with the internal DC/DC converter enabled at supply voltages above 4.5 V. The signal channels have excellent timing specifications with propagation delay The time it takes to transmit a signal from one place to another. Propagation delay is dependent solely on distance and two thirds the speed of light. Signals going through a wire or fiber generally travel at two thirds the speed of light. Contrast with nodal processing delay. less than 55 nanoseconds and channel-to-channel matching better than three nanoseconds. All three ADuM24x products carry a 2.5 KV isolation rating. Each product varies by the directionality di·rec·tion·al adj. 1. Of or indicating direction: an automobile's directional lights. 2. Electronics Capable of receiving or sending signals in one direction only. 3. of each channel. The ADuM5240 has two signal outputs on the same side as the power output. The ADuM5241, with signal channels in each direction, is ideal for bi-directional communications, such as an RS-232 transceiver (TRANSmitter reCEIVER) An electronic device or circuit that transmits and receives analog or digital signals. It comes in many forms; for example, a transponder on a satellite, a network adapter in the computer or the circuits in a cellphone. , that require isolated power for interface electronics. The ADuM5242, with the two signal outputs on the same side as the power input, is ideal for power supply applications that employ secondary side control and require isolated power to initiate start-up. About ADI's iCoupler Digital Isolators Isolation devices are used in a wide range of applications to protect people and equipment from unsafe voltage levels and disruptive noise sources. Analog Devices' iCoupler isolation technology employs chip-scale, micro-transformers in contrast to the LEDs and photodiodes used in optocouplers. Compared to optocouplers, iCoupler products consume less power, achieve higher data rates and provide more precise timing, yet still provide isolation ratings of up to 5 kV. Because the micro-transformer structures are integrated on semiconductor substrates, iCoupler products can achieve high levels of integration enabling greater functionality, smaller size and lower cost. Underscoring the scalability and flexibility of the iCoupler technology, isoPower is the latest development in ADI's digital isolation product portfolio. Pricing and Availability The ADuM524x digital isolators are sampling to lead customers now with samples to the open market scheduled for July 2006. Each of the three devices is available in Pb-free 8-lead SOIC packaging and is priced at $2.95 per unit in 1,000-piece quantities.
