ADUM252N1BRIZ

Overview

The ADUM252N1BRIZ is a robust digital isolator from Analog Devices, featuring five channels in a 3/2 configuration within a 16-lead SOIC package. It operates on a supply voltage range of 1.7 V to 5.5 V with a typical quiescent current of 13.7 mA. The device supports data rates up to 150 Mb/s and provides an insulation voltage of 5000 Vrms using magnetic coupling technology. Key electrical parameters include a propagation delay of 7.2 ns, a common-mode transient immunity of 75 kV/µs, and a pulse width distortion of 500 ps. It functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for signal transmission without optical components.
• Provides high common-mode transient immunity to protect against noise interference.
• Supports level translation between different voltage domains within the specified operating range.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing robust signal integrity
• Power metering applications with high-voltage separation

Procurement Notes

Verify the specific suffix '1' confirms the 3-forward/2-reverse channel configuration before ordering. Ensure the SOIC-16 package dimensions match the PCB footprint requirements. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Check for moisture sensitivity levels to determine proper storage and handling procedures during manufacturing.

Selection Notes

Select this component when a five-channel unidirectional isolator is required in a compact surface-mount package. It is suitable for designs needing high-speed data transfer up to 150 Mbps with significant voltage isolation barriers. Consider the power consumption characteristics relative to other options in the ADUM252N series if thermal management is critical.

Part Context

This part belongs to the ADUM252N family of general-purpose digital isolators. These devices are designed to replace traditional optocouplers by offering superior performance in speed, power consumption, and reliability. The family includes various channel configurations to suit different interface needs while maintaining consistent isolation specifications.

Replacement Considerations

Direct substitutes within the same family include ADUM252N0BRIZ, which shares identical electrical characteristics but differs in channel directionality configuration. Verify pin compatibility and functional equivalence before swapping parts in existing designs.
