Digital isolators add more channels in space-constrained designs

iCoupler devices reduce board space by up to 70% and cut costs by as much as 50%

The four-channel ADuM5401/2/3/4 iCoupler digital isolators with isoPower are offered as a better choice over discrete solutions, such as optocouplers with external dc/dc converters, because their small 10 x 10-mm surface-mount packages can reduce board space by up to 70% and cut costs by as much as 50%. In addition, the devices come with safety pre-approvals, allowing designers to realize faster design times as compared to discrete-based solutions, which require time-consuming safety approvals that can delay time to market.

The on-board isoPower isolated dc/dc converter provides up to 500 mW of regulated, isolated power and can operate at either 5.0 or 3.3 V. A version with two channels (ADuM520x) and a version that features only the isoPower isolated power supply (ADuM5000) will be released later this year. (ADuM540x, $5 ea/1,000 — available now.)
