ADUM3400CRWZ-RL

Overview

The ADUM3400CRWZ-RL is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mbps. The device provides 2500 Vrms isolation voltage with a common-mode transient immunity of 25 kV/µs. Key electrical parameters include a maximum propagation delay of 32 ns, typical rise/fall times of 3 ns, and a pulse width distortion of 11.1 ns. It functions in temperatures from -40°C to +105°C and is housed in a 16-lead SOIC wide package.

Feature Summary

• Integrates four independent bidirectional channels for general-purpose signal isolation
• Employs on-chip transformer-based magnetic coupling for high reliability
• Provides robust common-mode transient immunity against fast switching noise
• Supports standard logic levels across isolated boundaries without external components

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment safety barriers
• Power metering and energy monitoring circuits
• Inverter and motor control gate drive interfaces

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check current availability as distribution may be limited or subject to factory special orders. Ensure the 16-SOIC footprint matches the target PCB design constraints.

Selection Notes

Select this component for applications demanding high-speed digital isolation with low power consumption. The 90 Mbps rate suits most industrial communication protocols. Consider the 16-pin SOIC package for surface-mount assembly compatibility. Evaluate thermal performance within the specified operating temperature range during system design.

Part Context

This part belongs to the ADuM3400 series of quad-channel digital isolators from Analog Devices. It represents the standard version of the family, distinguished by its bidirectional channel configuration. The series leverages silicon dioxide insulation and copper coils for signal transmission.

Replacement Considerations

Official substitutes include ADUM3401CRWZ-RL and ADUM3402CRWZ-RL. Verify channel directionality and pinout compatibility before substitution.
