ADUM220N1BRWZ

Overview

The ADUM220N1BRWZ is a dual-channel digital isolator from Analog Devices, housed in a 16-lead SOIC package. It provides robust isolation with a rated insulation voltage of 5000 Vrms and a common-mode transient immunity of 75 kV/µs. The device supports data rates up to 150 Mb/s with a typical propagation delay of 7.8 ns. Operating on a single supply voltage between 2.25 V and 5.5 V, it features unidirectional signal flow. The component is designed for industrial applications, offering high reliability with a pulse width distortion of 0.3 ns.

Feature Summary

• Provides galvanic isolation between circuits using magnetic coupling technology
• Ensures signal integrity through high common-mode transient immunity
• Supports high-speed digital communication with low propagation delay
• Operates reliably across extended industrial temperature ranges

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering and energy management
• Automotive electronics interfaces

Procurement Notes

Verify the specific suffix 'N1' to confirm the 150 Mbps data rate and 75 kV/µs CMTI specifications, as variants exist within the ADUM220 family. Ensure the SOIC-16 package matches your PCB footprint requirements. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation before finalizing procurement decisions.

Selection Notes

Select this component when high-speed bidirectional data transfer is not required, as it is unidirectional. It is suitable for designs needing robust noise immunity in electrically noisy environments. Consider the 16-SOIC package size for space-constrained layouts. Verify that the 5000 Vrms isolation rating meets the safety standards of your target application domain.

Part Context

This part belongs to the ADuM220 series of digital isolators, which utilize iCoupler technology. The series offers various channel configurations and speed grades. The ADUM220N1BRWZ specifically targets applications requiring high-speed performance combined with high isolation voltage ratings in a standard surface-mount package.

Replacement Considerations

The ADUM2200BRWZ is a similar dual-channel isolator but operates at lower speeds (10 Mbps). The ADUM2201BRWZ also offers 10 Mbps operation. Direct pin-compatible replacements with identical electrical characteristics may require verification against the latest Analog Devices substitution guides.
