Analog Devices ADuM1442

The ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM14471 are micropower, 4-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. When ENx = 1 (internal refresh disabled), the current per channel drops to less than 1 µA. The ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 family of quad 2.5 kV digital isolation devices are packaged in a small 16-lead QSOP and 20-lead SSOP, freeing almost 70% of board space compared to isolators packages in wide body SOIC packages.
