Robust iCoupler® Digital Isolators

Digital isolator devices from Analog Devices improve signal reliability to guarantee safe system functionality in noisy environments

Image of ADI's Robust iCoupler® Digital IsolatorsADI introduces the industry’s most robust digital isolator series with the best combination of signal reliability, safety, and performance currently available. Based on ADI’s patented iCoupler digital isolation technology, the isolator devices ensure safe system performance for applications operating in noisy, harsh, and unpredictable healthcare and industrial environments.

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, ADI's iCoupler digital isolators feature the highest surge protection in the industry tested at 16 kVpk and withstand voltage ratings up to 5 kVRMS. And unlike other digital isolators, the robust iCoupler digital isolators can replace bulky optocouplers in harsh medical environments with a more compact solution.

Precision robotic arms operate in unforgiving industrial factory floor environments. Modern high-speed communications used in factory automation must be isolated from electrical noise caused by arc welding and other equipment in order to avoid signal interference. ADI’s iCoupler digital isolators provide high noise immunity and surpass previous digital isolator options to ensure signal integrity. ADI’s isolation components provide outstanding performance and proven galvanic isolation with more than 1.4 billion channels shipped and growing. By combining high-speed CMOS and monolithic air core transformer technology and an on-off-keying (OOK) architecture, the new digital isolators offer the highest available noise immunity, lowest EMI, and highest surge capability for broad market appeal. Multiple products are in production today with versions in different packages and channel counts forthcoming.
