Isolation Technology

With nearly 2 billion channels shipped, ADI’s digital isolation technology offers compact, robust and reliable solutions that solve our customers’ data transmission and power isolation challenges while meeting strict safety standards. iCoupler digital isolators meet a wide range of creepage/clearance requirements, while the isolated μModule platform reliably integrates galvanic isolation, discrete components, ICs, and power onto a single substrate PCB, resulting in products that require no external components. The broad portfolio offers solutions spanning data isolators, isoPower® solutions, high power isolated dc-to-dc converters, isolated field bus and peripheral communications, gate drivers from IGBT to GaN, isolated switches, and isolated data converter controllers, as well as isolated Σ-Δ modulators, isolated amplifiers, and energy metrology. Utilizing the award-winning iCoupler® and isoPower® technologies and isolated μModule, these isolation solutions enable designs without the constraints found in optocouplers.
