ADUM1245ARZ

Overview

The ADUM1245ARZ is a micropower, dual-channel digital isolator based on Analog Devices' iCoupler technology. It provides bidirectional communication with a data rate of up to 2 Mbps and an insulation voltage of 3750 Vrms. The device operates within a supply voltage range of 2.25 V to 3.6 V, drawing a typical operating current of 366 uA. It features a propagation delay of 180 ns and functions reliably across an extended temperature range from -40°C to +125°C. Housed in an 8-lead SOIC package, it utilizes magnetic coupling for isolation.

Feature Summary

• Micropower operation suitable for energy-efficient designs
• Bidirectional communication channels for flexible signal routing
• High common-mode transient immunity for noise-resistant performance

Applications

• Industrial automation systems requiring isolated interfaces
• Medical equipment needing galvanic isolation
• Power metering applications with high-voltage separation needs

Procurement Notes

Verify the specific suffix 'ARZ' to confirm the RoHS-compliant lead-free status and tube packaging format. Ensure the ordering quantity matches the factory tube pack size of 98 units if standard packaging is required. Cross-reference the datasheet revision date to confirm compatibility with your design specifications before finalizing procurement orders.

Selection Notes

Select this component when low power consumption is critical alongside moderate data rates up to 2 Mbps. The 3750 Vrms isolation rating supports applications requiring robust safety barriers. Consider the 8-lead SOIC package for surface-mount assembly constraints. Verify that the 2.25 V to 3.6 V supply range aligns with the system's logic levels and power budget requirements.

Part Context

This part belongs to the ADUM1245 series of iCoupler digital isolators. It shares the same core architecture as other variants in the family but differs in packaging and specific electrical characteristics. The series is designed to replace traditional optocouplers in various interface applications while offering superior performance and reliability.

Replacement Considerations

Check for direct substitutes within the ADUM124x family that may offer different packaging options or slight variations in propagation delay. Ensure any replacement maintains the 3750 Vrms isolation rating and 2 Mbps data rate capability to preserve system functionality.
