Data Sheet 1 kV, Dual Channel Digital Isolators ADuM7240/ADuM7241 FEATURES Narrow-body, RoHS-compliant, 8-lead SOIC Safety and regulatory approvals UL recognition UL 1577: 1000 V rms for 1 minute Low power operation 5 V operation 2.4 mA per channel maximum at 0 Mbps to 1 Mbps 11.8 mA per channel maximum at 25 Mbps 3.3 V operation 1.7 mA per channel maximum at 0 Mbps to 1 Mbps 8.2 mA per channel maximum at 25 Mbps Bidirectional communication Up to 25 Mbps data rate (NRZ) 3 V/5 V level translation High temperature operation: 105°C High common-mode transient immunity: >15 kV/μs APPLICATIONS General-purpose multichannel isolation Data converter isolation Industrial field bus isolation GENERAL DESCRIPTION The ADuM7240/ADuM72411 are dual 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 ADuM7240/ADuM7241 dual 1 kV digital isolation devices are packaged in a narrow-body 8-lead SOIC. The ADuM7240/ ADuM7241 offer a cost-effective option compared to 2.5 kV or 5 kV isolators where only functional isolation is needed. Like other Analog Devices isolators, the ADuM7240/ADuM7241 offer very low power consumption, consuming one-tenth to one-sixth the power of comparable isolators at data rates up to 25 Mbps.
