Product details
Overview
ADUM4402BRWZ-RL from Analog Devices is a 5 kVRMS quad-channel digital isolator with bidirectional communication, 3.3 V/5 V level translation, and output enable functionality. It delivers 90 Mbps data rate, <2 ns pulse width distortion, and >25 kV/µs common-mode transient immunity. Used in medical equipment, motor drives, and isolated power supply feedback loops.
For engineers reviewing the ADUM4402BRWZ-RL datasheet, ADUM4402BRWZ-RL pinout, ADUM4402BRWZ-RL application, or ADUM4402BRWZ-RL equivalent, this page provides verified specifications, package mapping, safety certifications (UL 1577, VDE 0884-17), real-world timing behavior, and validated alternative options for industrial and medical isolation designs.
Technical Context
The ADUM4402BRWZ-RL implements iCoupler® monolithic air-core transformer technology across four independent channels, enabling galvanic isolation without optocoupler aging or LED drive complexity. Its patented refresh circuit ensures DC correctness during power-up, power-down, and static input conditions.
It supports asymmetric supply operation (3.3 V/5 V or 5 V/3.3 V), features integrated input glitch filtering, and maintains precise channel-to-channel matching (<2 ns skew) and low propagation delay variation (<3 ps/°C). All channels share identical electrical characteristics per grade (B-grade here).

FAQ
What safety certifications does the ADUM4402BRWZ-RL hold?
The ADUM4402BRWZ-RL is certified to UL 1577 (5000 VRMS), DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 Vpeak, IEC 60601-1 (2 MOPP), and IEC 62368-1. These approvals validate its use in patient-connected medical devices and industrial equipment requiring reinforced insulation.
How does the ADUM4402BRWZ-RL handle power-up and static input conditions?
The ADUM4402BRWZ-RL incorporates a patented refresh circuit that actively monitors input states and retransmits them across the isolation barrier during static conditions or power transitions. This ensures DC correctness without external supervision-critical for medical monitoring and closed-loop power control.
Can the ADUM4402BRWZ-RL operate with different supply voltages on each side?
Yes. The ADUM4402BRWZ-RL supports mixed-supply operation: 3.3 V on Side 1 and 5 V on Side 2, or vice versa. Input thresholds adapt accordingly (VIH = 2.0 V at 5 V, 1.6 V at 3.3 V), enabling seamless level translation in heterogeneous systems.
What is the maximum data rate supported by the ADUM4402BRWZ-RL?
The ADUM4402BRWZ-RL supports up to 90 Mbps (NRZ) at the C-grade performance level. At lower speeds (≤2 Mbps), it draws only 1.4 mA/channel at 5 V or 0.9 mA/channel at 3.3 V-ideal for power-constrained designs.
Does the ADUM4402BRWZ-RL include protection against electrical noise?
Yes. The ADUM4402BRWZ-RL integrates input glitch filtering and achieves >25 kV/µs common-mode transient immunity. Its iCoupler® architecture inherently rejects magnetic interference, making it robust in motor drive and switch-mode power supply environments.
