Isolation ICs

Analog Devices’ portfolio of high voltage, low latency digital isolators uses magnetic iCoupler® and capacitive isolation technology to enable engineers to deliver robust, low cost solutions for EV, grid infrastructure, industrial automation, and motor drive applications. Products meet stringent safety standards including our intrinsically safe certified digital isolators for designs in hazardous areas. Options include different channel counts, package variants, and integrated DC-to-DC converters. ADI also has versions with automotive certification.

Analog Devices’ isolated ADCs integrate precision conversion with our proprietary high voltage iCoupler® isolation technology to deliver robust high performance isolated current and voltage measurement. Typical applications include motor drives, solar inverters, battery management, factory automation, instrumentation, EV chargers, and traction inverters.

Analog Devices’ isolated amplifiers are high performance components designed to safely and accurately measure analog signals across high voltage domains. These amplifiers combine a precision analog front end with robust digital isolation using ADI’s iCoupler® technology. Applications include motor control, power inverters, battery management systems, and solar inverters.

Analog Devices’ isoPower® technology utilizes proprietary iCoupler® chip scale transformers to integrate isolated DC-to-DC converters with data isolation and other functions into a single package. This enables system designers to optimize their isolated designs for cost, size, power, performance, and reliability.

Analog Devices’ small form factor isolated gate drivers are designed for the higher switching speeds and system size constraints required by power switch technologies such as SiC (silicon carbide) and GaN (gallium nitride), while still providing reliable control over switching characteristics for IGBT (insulated gate bipolar transistor) and MOSFET (metal oxide semiconductor field effect transistor) configurations for high-side and low-side switches. These isolated gate drivers leverage ADI’s proven iCoupler® isolation technology combined with high-speed CMOS and monolithic transformer technology to enable ultralow propagation delay without sacrificing common-mode transient immunity (CMTI) performance. High pulse fidelity architecture enables motor power efficiency to meet new required efficiency levels, and superior timing performance stability reduces voltage distortion, as well as harmonic and output power content on solar inverters.

Analog Devices’ isolated interface products combine high performance isolation with robust communication protocols, ensuring safe, fast, and reliable data transfer in harsh industrial, automotive, energy, and medical environments. Our portfolio of communication products includes support for RS-232, RS-485, USB, CAN, I²C, SPI, and now industry-leading high speed gigabit LVDS. Many of our isolated interface products also integrate an isolated DC-to-DC converter that helps customers optimize their designs for cost and size.
