Product details
Overview
ADUM4401BRWZ from Analog Devices is a 5 kVRMS quad-channel digital isolator with bidirectional communication, 90 Mbps data rate, 2 ns max pulse width distortion, and 3.3 V/5 V level translation capability. It provides reinforced isolation for high-voltage industrial interfaces such as motor drive gate drivers and isolated power supply feedback loops.
For engineers reviewing the ADUM4401BRWZ datasheet, ADUM4401BRWZ pinout, ADUM4401BRWZ application, or ADUM4401BRWZ equivalent, this page delivers verified specifications, safety-certified package details (RW-16 SOIC wide-body), functional channel configuration, and real-world design implications for medical, motor control, and power conversion systems.
Technical Context
The ADUM4401BRWZ implements iCoupler® monolithic air-core transformer technology across four independent isolation channels, enabling simultaneous bidirectional signal transfer with precise timing control. Its architecture supports mixed-supply operation (3.3 V/5 V on opposite sides) and includes an input glitch filter plus patented refresh circuitry to guarantee DC correctness during power-up, power-down, and idle states.
This variant features asymmetric channel directionality: Channels A–C are input-to-output (Side 1 → Side 2), while Channel D is output-to-input (Side 2 → Side 1). It delivers 25 kV/µs common-mode transient immunity and operates reliably from −40°C to +105°C with reinforced insulation rated at VIORM = 645 Vpeak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 90 Mbps (NRZ) - supports high-speed SPI, RS-485 transceiver control, and PWM feedback in servo drives. |
| Isolation Rating | 5000 VRMS for 1 minute - certified for reinforced insulation per UL 1577, IEC/EN/CSA 62368-1, and IEC 60601-1 (2 MOPP). |
| Pulse Width Distortion | ≤2 ns (C grade) - ensures minimal duty-cycle error in clock distribution and PWM timing-critical applications. |
| Supply Voltage Range | 3.0 V to 5.5 V per side - enables interoperability between legacy 5 V logic and modern 3.3 V microcontrollers without external level shifters. |
| Common-Mode Transient Immunity | >25 kV/µs - maintains signal integrity in noisy motor drive environments with fast-switching IGBTs or SiC MOSFETs. |
| Propagation Delay Skew | ≤2 ns (codirectional) - guarantees synchronized timing across all four channels for multi-phase gate driver enable signals. |
| Output Enable Function | Dedicated VE1 (Side 1) and VE2 (Side 2) pins - allows dynamic channel disabling for low-power sleep modes or fault-safe shutdown sequences. |
Pinout & Package
ADUM4401BRWZ uses a 16-lead SOIC wide-body package (RW-16) with 7.8 mm minimum creepage and clearance, optimized for reinforced insulation in industrial and medical designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | VDD1 / VDD2 | Independent 3.0–5.5 V supplies for isolated input (Side 1) and output (Side 2) domains - enables level translation and dual-rail system integration. |
| 2, 8, 9, 15 | GND1 / GND2 | Separate ground references per side - prevents ground loop coupling and preserves noise immunity across isolation barrier. |
| 3–5, 11–14 | VIA–VIC, VOD, VOC–VOA | Three unidirectional inputs (A–C) and three unidirectional outputs (C–A) on Side 1→2; one reverse-direction output (D) on Side 2→1 - defines ADUM4401's 3+1 channel asymmetry. |
| 6, 7, 10 | VOD, VE1, VE2 | VOD is Side 2 output for Channel D; VE1 controls Side 1 outputs; VE2 controls Side 2 outputs - enables selective channel gating without affecting other channels. |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Monolithic air-core transformers replace optocouplers - eliminates LED aging, improves CMTI, and achieves 10× lower power vs. opto-based solutions at 10 Mbps. |
| Reinforced safety certification | UL, VDE, CQC, and CSA approvals for 645 Vpeak working voltage - qualifies for Class I medical equipment (IEC 60601-1) and industrial PLCs (IEC 61010-1). |
| Dynamic power scaling | Quiescent current ≤0.83 mA/channel at 3.3 V (0 Mbps); ≤20 mA/channel at 90 Mbps - reduces thermal load in compact enclosures. |
| Glitch-filtered inputs | Integrated noise suppression on all input pins - prevents false triggering from EFT bursts or radiated RFI in factory automation environments. |
| Refresh circuitry | Automatic DC restoration during signal inactivity - ensures deterministic output state during MCU reset or bus idle periods without external watchdog timers. |
Applications
| Motor Drive Control | Isolated Power Supply Feedback |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8440AB-B-IS | Capacitive isolation; 5 kVRMS; 1 Mbps to 150 Mbps; no integrated refresh circuit. | Lacks guaranteed DC correctness during extended idle - requires external watchdog or periodic toggling for safety-critical hold states. | Prefer when maximum data rate >90 Mbps is required and DC stability is managed at system level. |
| ISO6741QDWR | Capacitive isolation; 5 kVRMS; 50 Mbps max; AEC-Q100 qualified; 3.3 V only. | Lower speed ceiling and automotive-focused qualification - not suitable for 90 Mbps motor control or medical imaging telemetry. | Select only for automotive body electronics where AEC-Q100 compliance is mandatory and 50 Mbps suffices. |
Compared with SI8440AB-B-IS and ISO6741QDWR, the ADUM4401BRWZ uniquely combines 90 Mbps performance, guaranteed DC correctness via refresh, and broad safety certifications - making it optimal for industrial and medical systems demanding both speed and fail-safe behavior without firmware overhead.

FAQ
What is the maximum data rate supported by ADUM4401BRWZ?
The ADUM4401BRWZ supports a maximum data rate of 90 Mbps in NRZ format. This rating applies to the C-grade version (denoted by 'B' in the part number suffix) and is validated across the full operating temperature range (−40°C to +105°C) with CL = 15 pF loading. At lower speeds (e.g., 10 Mbps), supply current drops significantly - enabling power-sensitive designs without sacrificing timing fidelity.
Does ADUM4401BRWZ support level translation between 3.3 V and 5 V logic domains?
Yes, ADUM4401BRWZ fully supports bidirectional level translation: VDD1 may be 3.3 V while VDD2 is 5 V, or vice versa. The input thresholds (VIH = 2.0 V min at 5 V supply, 1.6 V min at 3.3 V) and output drive strength (VOH ≥ VDDx − 0.4 V at 3.2 mA load) ensure interoperability across mixed-voltage systems without external level shifters - critical for interfacing legacy 5 V peripherals with modern 3.3 V MCUs.
How does the output enable (VE1/VE2) function work in ADUM4401BRWZ?
ADUM4401BRWZ provides two independent output enable pins: VE1 controls all Side 1 outputs (VOA–VOC), and VE2 controls all Side 2 outputs (VOA–VOD). When asserted high (or left floating), outputs drive actively; when pulled low, they enter high-impedance state within 8 ns. This allows dynamic channel disabling for power gating, fault isolation, or bus arbitration - with propagation delay skew <2 ns between enabled channels.
What safety certifications apply to ADUM4401BRWZ?
ADUM4401BRWZ carries UL 1577 (5000 VRMS/1 min), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), IEC/CSA 61010-1, CQC GB 4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) approvals. Its RW-16 package is rated for reinforced insulation up to 645 Vpeak, supporting medical, industrial, and energy applications requiring stringent creepage (>7.8 mm) and clearance compliance.
Is ADUM4401BRWZ pin-compatible with other ADuM440x variants?
No - ADUM4401BRWZ has a unique pinout distinct from ADUM4400 and ADUM4402. Specifically, Pin 6 is VOD (output) and Pin 7 is VE1 (enable) on Side 1, whereas ADUM4400 uses Pin 6 as NC and ADUM4402 swaps VE1/VE2 placement. PCB layout must match ADUM4401BRWZ's 3-input/1-output asymmetry (A–C inputs, D output on Side 2) and cannot reuse footprints from other family members without redesign.
