Analog Devices Unveils Single-package Solution for Medical-grade Data and Power Isolation

These new iCoupler quad-channel isolators are a better choice over discrete solutions, such as optocouplers with external dc-to-dc converters, because they can both cut costs and reduce board space by as much as 50 percent, and speed time-to-market.

The ADuM640x quad-channel isolator family includes the ADuM6400, ADuM6401, ADuM6402, ADuM6403, and ADuM6404 digital isolation products. The quad-channel isolators offer 5-kV rms medical-grade isolation (IEC 60601-1 approvals pending) and four independent isolation channels in various channel configurations and data rates. The onboard isoPower isolated dc-to-dc converter provides up to 500 mW of regulated, isolated power and can operate at either 5.0 V or 3.3 V. This eliminates the need for a separate, isolated dc-to-dc converter in low-power, isolated designs. The ADuM640x also includes a thermal shutdown feature to ensure safe operation.

Also now available is the ADuM440x family of quad-channel digital isolators that feature enhanced system-level ESD (electrostatic discharge) protection with 5-kV rms medical-grade isolation (IEC 60601-1 approvals pending). The ADuM440x family includes the ADuM4400, ADuM4401, and ADuM4402 digital isolation products that differ by channel configuration.
