Analog Devices offers a wide range of interface products that include solutions covering many industry communications standards. Digital isolators, isolated transceivers, and isolated A/D converters utilizing the award winning iCoupler® and isoPower® technologies are also available to implement isolation in designs without many of the constraints found in optocouplers. Other interface devices include keypad controllers, level translators, and high voltage protection products, such as channel protection, fault protection, overvoltage protection, and latch-up proof switches and multiplexers.

Isolated A/D Converters

In the motor control arena, ADI’s converters solve the challenges associated with current and voltage monitoring, optical encoder feedback, and resolver-to-digital conversion.

Isolated Controller Area Network (CAN)

ADI isolated controller area network transceivers provide the differential physical layer interface between the data layer link, hardware, and physical wiring of the CAN bus.

Isolated Gate Drivers

Analog Devices’ isolated gate driver portfolio offers designers performance and reliability advantages over designs utilizing optocouplers or pulse transformers.

Isolated I2C Isolators

Analog Devices’ family of isolated I2C isolators support a complete isolated I2C interface. This portfolio is based on our iCoupler® chip scale transformer technology.

Isolated LVDS

ADI low voltage differential signaling (LVDS) isolators, based on iCoupler® magnetic isolation technology, offer designers robust high speed differential signaling up to 600 Mbps.

Isolated RS-232

Analog Devices offers a wide range of RS-232 transceivers, and our isoPower® DACs, as well as our iCoupler® technology, help create an isolated RS-232 environment.

Isolated RS-485

Analog Devices offers a wide range of standard RS-485/RS-422 transceivers and iCoupler® isolated RS-485/RS-422 transceivers to suit many applications.


ADI isoPower® technology utilizes proprietary iCoupler® chip scale transformers to integrate isolated dc-to-dc converts with data isolation into a single package.

Linear Isolators

Linear isolators provide power supply designers with a higher performing, single chip alternative to isolation techniques based on optocouplers and shunt regulators.


ADI SPIsolator® digital isolators are dedicated serial peripheral interface (SPI) isolators that have a small footprint, simple design, fast speed, and high data integrity.

Standard Digital Isolators

ADI standard digital isolators enable designers to apply isolation in designs without the cost, size, performance, and reliability constraints found in optocouplers.

USB Isolators

Based on iCoupler® technology, ADI’s USB 2.0 compliant isolators are fully isolated to 1.5 Mbps and 12 Mbps, and help decrease system cost, design size, and design time.
