FEATURES
APPLICATIONS
GENERAL DESCRIPTION The ADuM7440/ADuM7441/ADuM74421 are 4-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technologies, these isolation components provide outstanding performance characteristics superior to the alternatives, such as optocoupler devices and other integrated couplers. The ADuM7440/ADuM7441/ADuM7442 family of quad 1 kV digital isolation devices is packaged in a small 16-lead QSOP. While most 4-channel isolators come in 16-lead wide SOIC packages, the ADuM7440/ADuM7441/ADuM7442 free almost 70% of board space and yet can still withstand high isolation voltage and meet UL regulatory requirements. In addition to the space savings, the ADuM7440/ADuM7441/ADuM7442 offer a lower price than 2.5 kV or 5 kV isolators where only functional isolation is needed. This family, like many Analog Devices isolators, offers very low
power consumption, consuming one-tenth to one-sixth the power of
comparable isolators at comparable data rates up to The ADuM7440/ADuM7441/ADuM7442 isolators provide 1 Protected by U.S. Patents 5,952,849, 6,873,065 and 7,075,329. Other patents pending. |
