ADUM1280WCRZ-RL7

Overview

The ADUM1280WCRZ-RL7 is a dual-channel digital isolator manufactured by Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It provides bidirectional signal isolation with a rated insulation voltage of 3000 Vrms and supports data rates up to 100 Mb/s. The device features a propagation delay of 24 ns and operates within an extended temperature range from -40°C to +125°C. Packaged in an SOIC-8 surface-mount format, it requires a supply current of 20 mA per channel. This component is AEC-Q100 qualified for automotive applications.

Feature Summary

• Bidirectional signal transmission capability across two isolated channels
• High-speed data processing supporting rates up to 100 Mb/s
• Robust magnetic coupling isolation ensuring safety compliance

Applications

• Automotive electronic control units requiring high-voltage isolation
• Industrial communication interfaces such as RS-485 and CAN bus
• Medical equipment needing reinforced galvanic isolation

Procurement Notes

Verify the specific suffix RL7 against official Analog Devices documentation to confirm reel packaging specifications. Confirm that the W variant meets the required wide-body package dimensions for your PCB layout. Ensure the AEC-Q100 qualification aligns with your target application standards before finalizing procurement orders.

Selection Notes

Select this component when bidirectional isolation is required for high-speed digital signals. The 100 Mb/s data rate distinguishes it from lower-speed variants like the ADUM1241. Consider the 20 mA power consumption relative to thermal constraints in dense layouts compared to lower-power alternatives.

Part Context

This part belongs to the ADUM1280 series of dual-channel digital isolators. It shares the SOIC-8 footprint with other family members but differs in speed and directionality. The ADUM1286 offers unidirectional options, while the ADUM1200 provides different speed ratings. All utilize proprietary iCoupler technology for compact isolation solutions.
