Digital Isolators

Description

iCoupler® isolators eliminate optocoupler limitations. Combining high-speed CMOS with chip-scale micro transformers (learn more), this family of isolation products provides substantial improvements in terms of cost, size, performance, power, reliability and ease-of-use. iCoupler products are offered in a wide range of performance, channel configuration, and price levels to fit almost any application.

Analog Devices' Digital Isolation Update quarterly email will keep you posted on the introduction of a wide array of new iCoupler® isolation products, including gate drivers, transceivers, and multi-channel digital isolators, as well as isoPower™ isolated, integrated DC/DC converters.

Informative Links
This table contains both the Isolator Products as well as product families that complement the iCoupler® family.

* Channel configuration refers to the directionality of the isolation channels. For products with integrated, isolated power, the second number corresponds to the number of inputs on the side with the isolated power. For example, "2/1" means two channels communicate in one direction while the third channel communicates in the reverse direction, with two inputs on the non-isolated supply side, and one input on the isolated supply side.

* Please refer to application note AN-793. These parts are intended for use in systems deployed in environments subject to extreme ESD conditions, e.g., per IEC-61000-4-x. Most applications do not require the extra protection provided by these devices and will meet ESD, fast transient, etc. reliability requirements through careful board layout, as explained in AN-793.

* Channel Config Note: Channel configuration refers to the directionality of the isolation channels. The first number corresponds to the number of inputs on the side with the non-isolated supply, and the second number corresponds to the number of inputs on the side with the isolated power output. For example, "0/2" means the inputs of the two data channels are on the same side as the isolated power output.
