Analog Devices Inc. (ADI) has announced what it describes as the industry's most robust digital isolator series that ensure safe system performance for applications operating in noisy, harsh and unpredictable healthcare and industrial environments. The isolator devices are based on ADI's patented iCoupler digital isolation technology.

Advances in healthcare technology are pushing design boundaries by requiring wired patient monitors to function continuously during defibrillation. These high-voltage transients put a great burden on designing a dependable, connected medical system. To protect data signals in this unpredictable environment, the iCoupler digital isolators claim to feature the highest in industry surge protection tested at 16kVpk and withstand voltage ratings up to 5kVrms. And unlike other digital isolators, ADI's iCoupler digital isolators can replace bulky optocouplers in harsh medical environments with a more compact solution, stated the company.

In addition, the device delivers 150Mb/s throughput, 13ns max propagation delay, 100kV/us CMTI; supply range of 1.7V to 5.5V; and supports one to four input channels, choice of default state, and input/output disable, pin compatible to prior generations.

ADI's iCoupler digital isolators promise to deliver high noise immunity and surpass previous digital isolator options to ensure signal integrity. By combining high-speed CMOS and monolithic air core transformer technology and an on-off-keying (OOK) architecture, the digital isolators offer the highest available noise immunity, lowest EMI and highest surge capability for broad market appeal, ADI stated. Multiple products are in production with versions in different packages and channel counts forthcoming.
