Analog Devices Inc. ADuM3210/ADuM3211 Dual-Channel, Digital Isolators

Analog Devices ADuM3210/ADuM3211 dual-channel digital isolators with iCoupler® technology combine high-speed CMOS and monolithic transformer technology to achieve outstanding performance characteristics superior to alternatives such as optocoupler devices. The ADuM3210/ADuM3211 isolators provide two independent isolation channels in two-channel configurations with data rates up to 25Mbps. They operate with 3.3V or 5V supply voltages on either side, providing compatibility with lower voltage systems, as well as enabling voltage translation functionality across the isolation barrier. The ADuM3210/ADuM3211 digital isolators are well-suited for size-critical multichannel isolation, SPI interface/data converter isolation, RS-232/RS-422/RS-485 transceiver isolation, digital field bus isolation, and hybrid electric vehicles.

Analog Devices EVAL-1CH2CHEBZ Evaluation Board is designed to support single and dual channel iCoupler® standard data isolators in 8-lead SOIC packages. The EVAL-1CH2CHEBZ board assesses the entire range of iCoupler data transfer functions. The board also independently powers each side of the iCoupler isolator and applies high differential voltages between the two sides.
