Analog Devices Enables Isolated USB Connections for Medical and Industrial Equipment

iCoupler® Technology

With more than 250 million channels deployed, ADI’s proven iCoupler technology is based on chipscale transformers, rather than on the LEDs and photodiodes found in optocouplers. Transformers support higher data rates, consume less power, 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. iCoupler transformers are planar structures formed from CMOS and gold metal layers. A high breakdown polyimide layer underneath the gold layer insulates the top transformer coil from the bottom. CMOS circuits connected to the top coil and bottom coil provide the interface between each transformer and its external signals.
