Rating doubled for medical applications in proprietary isolation product

Electronics Technology

17 November 2004 Electronics Technology

Tailored to meet the needs of the medical instrumentation market, Analog Devices' ADuM240x component set has been engineered to increase the iCoupler digital isolation technology's isolation rating from 2,5 kV to 5,0 kV, while still providing 10 times the data rate and timing accuracy of 5,0 kV-rated optocouplers.

The ADuM240x product family consists of three products, each with a different combination of forward and reverse channels. Each is available in three performance grades supporting data rates of 1, 10, and 90 Mbps with appropriate timing accuracies for each data rate. All ADuM240x models carry a 5,0 kV isolation rating per UL1577 and are compliant with the medical safety standard IEC 60601-1.

iCoupler technology is a patented isolation technique based on chip-scale transformers rather than the LED/photodiode combination used in optocouplers. Performance advantages are achieved by eliminating the electro-optic conversions present in optocouplers. Also, since iCoupler transformers are fabricated directly on chip, channels can be efficiently integrated with each other and with other semiconductor functions more readily than optocouplers.
