NORWOOD, Mass. (PRWEB) July 21, 2008
The ADM3251E transceiver incorporates ADI's iCoupler® and isoPower™ isolation technologies and is the first surface mount RS-232 transceiver to feature full isolation of both the data lines and power. With a 2.5-kV isolation rating, the new RS-232 transceiver complies with industry-standard isolation regulations, including UL1577 and DIN VDE 0884-10, ensuring it will meet the robustness levels required in noisy operating environments such as isolated RS-232 diagnostic data ports in HVAC building control systems, industrial automation and control applications, point-of-sale equipment, programmable logic controllers, telecom and medical equipment. The SMT package reduces board space by 45 percent compared with traditional ICs and helps to accelerate the manufacturing process and lower system development costs.
With more than 150 million channels deployed throughout the industry, ADI's proven iCoupler technology is based on chip-scale transformers, rather than on the LEDs and photodiodes found in optocouplers. Transformers can support higher data rates and lower power consumption, and are more stable over life as compared to LEDs and photodiodes. By fabricating the transformers directly on-chip using wafer-level processing, iCoupler channels can be integrated with each other and other semiconductor functions at low cost.

isoPower™ DC-to-DC Converter
iCoupler digital isolators condition and drive data across transformers. ADI's isoPower dc-to-dc converter uses the same chipscale transformer technology, but instead of transmitting data, isoPower employs switches, rectifiers, and regulators to generate power that is isolated to the same degree as the data channels.
