Digital Isolation and Interface Technology

In today’s increasingly digitalized world ranging from Industry 4.0 to automotive electrification and digital health, Analog Devices is the expert where electrical meets electronic. With ubiquitous sensing and digitization, certified iCoupler digital isolators protect people, assets, and data from high voltages and hazardous environments. Our portfolio delivers best-in-class patented digital isolation technology for data, high power isolated dc-to-dc converters and communication protocols ranging from RS485, USB and CAN to gigabit LVDS and on to isolated gate drivers crafted for IGBT & SiC, isolated switches, and isolated Σ-Δ (sigma-delta) ADC modulators & amplifiers.

Trusted safety and data integrity

ADI’s Digital Isolation Solutions

Isolated Data

ADI’s iCoupler digital isolators enable robust solutions with the flexibility of up to six channels. Products meet stringent safety standards including the ability to isolate IS-IS with our intrinsically safe certified digital isolators. AEC Q100 automotive certified versions are also available.

  • Standard Digital Isolators
Isolated Power Conversion

isoPower chip-scale transformers remove design complexity and optimize power solutions. μModule devices create solutions that provide additional auxiliary isolated power. Isolated amplifiers provide power supply engineers with an upgrade in speed, temperature, and transient response over traditional optocoupler options.
