Product details
Overview
ADUM4401ARWZ from Analog Devices is a 4-channel, bidirectional digital isolator with reinforced 5 kVRMS insulation, 90 Mbps data rate, 2 ns max pulse width distortion, and 3.3 V/5 V level translation capability-used in motor drive control interfaces to isolate gate drivers from MCU logic.
For engineers reviewing the ADUM4401ARWZ datasheet, ADUM4401ARWZ pinout, ADUM4401ARWZ application, or ADUM4401ARWZ equivalent, this page delivers verified specifications, SOIC-16 RW-16 package details, safety certifications (UL, VDE, IEC 60601-1), and real-world isolation design context for medical, industrial, and power electronics systems.
Technical Context
The ADUM4401ARWZ implements iCoupler® monolithic air-core transformer technology across four independent channels, enabling true galvanic isolation without optocoupler aging or LED degradation. It supports asymmetric supply operation (e.g., 3.3 V on Side 1, 5 V on Side 2) and includes integrated input glitch filters and a patented refresh circuit for DC-correct output during signal static conditions or power sequencing.
Its architecture delivers high common-mode transient immunity (>25 kV/µs), precise channel-to-channel matching (≤2 ns skew), and output enable control on both sides-critical for synchronized shutdown in IGBT/SiC gate driver interfaces and isolated feedback loops in switched-mode power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 90 Mbps (NRZ) - supports high-speed serial communication in motor encoder interfaces and isolated ADC/DAC links. |
| Isolation Rating | 5000 VRMS for 1 minute - certified reinforced insulation per UL 1577, VDE 0884-17, and IEC 60601-1 (2 MOPP). |
| Pulse Width Distortion | ≤2 ns (C grade) - ensures timing integrity in PWM signal transmission for gate driver control. |
| Supply Voltage Range | 3.0 V to 5.5 V per side - enables mixed-voltage system interfacing (e.g., 3.3 V MCU to 5 V actuator logic). |
| Common-Mode Transient Immunity | >25 kV/µs - maintains signal fidelity in noisy high-dV/dt environments like inverter switching nodes. |
| Operating Temperature | −40°C to +105°C - qualified for under-hood automotive and industrial motor drive ambient conditions. |
| Power Consumption | 1.4 mA/channel @ 2 Mbps (5 V), 0.9 mA/channel @ 2 Mbps (3.3 V) - reduces thermal load in densely packed isolation barriers. |
Pinout & Package
ADUM4401ARWZ uses a 16-lead SOIC wide-body package (RW-16) with 7.8 mm minimum creepage and clearance, optimized for reinforced insulation in high-voltage PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | VDD1 / VDD2 | Independent 3.0–5.5 V supplies for isolated input/output sides - enables level translation and dual-rail operation. |
| 2, 8, 9, 15 | GND1 / GND2 | Dedicated ground references per isolation side - prevents ground loop coupling and preserves noise rejection. |
| 3–5, 11 | VIA–VIC, VOD | Unidirectional input channels (Side 1) and one output (Side 2) - defines ADUM4401's 3:1 input/output channel split. |
| 10, 12–14 | VE2, VOC–VOA | Output enable (active-high) and three outputs on Side 2 - allows dynamic disabling of isolated signals during fault conditions. |
| 6, 7, 11 | VOD, VE1, VID | Not present on ADUM4401ARWZ - pin 6 is VOD (output), pin 7 is VE1 (input-side OE), pin 11 is VID (input); confirmed per Figure 6 and Table 22. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional channel configuration | Supports full-duplex isolated communication without external direction control logic. |
| Output enable on both sides | VE1 (Side 1) and VE2 (Side 2) allow independent tri-state control of output banks for safe power-up/power-down sequencing. |
| Patented refresh circuit | Maintains correct DC output state during prolonged input inactivity or power cycling - eliminates need for external watchdog timers. |
| System-level ESD enhancement | Designed to meet IEC 61000-4-x standards (ESD, burst, surge) when implemented with proper board layout per AN-793. |
| Low propagation delay skew | ≤2 ns channel-to-channel matching - critical for time-aligned signals in multi-phase motor control and isolated clock distribution. |
Applications
| Motor Drive Control | Medical Isolated Data Acquisition |

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 |
|---|---|---|---|
| SI8641ED-B-IS | 4-channel, 100 Mbps, 3.75 kVRMS, SOIC-16, no output enable on input side | Lacks VE1 pin - limits flexible tri-state control during input-side power faults | Preferred where higher speed suffices and dual-side OE is not required; lower isolation rating requires revalidation for medical/industrial safety margins. |
| ISO6741-Q1 | 4-channel, 50 Mbps, 5 kVRMS, SOIC-16, automotive AEC-Q100 Grade 1 | Lower data rate and no 90 Mbps support; qualified for automotive temperature range only | Best for automotive body control modules needing AEC-Q100 compliance; unsuitable for high-speed motor control or medical timing-critical paths. |
Compared with SI8641ED-B-IS and ISO6741-Q1, ADUM4401ARWZ uniquely combines 90 Mbps speed, dual-side output enable, 5 kVRMS/645 VPEAK reinforced insulation, and guaranteed 2 ns pulse width distortion - making it optimal for high-fidelity, safety-critical isolation in industrial and medical systems requiring precise timing and robust certification.

FAQ
What is the maximum data rate supported by ADUM4401ARWZ?
ADUM4401ARWZ supports a maximum data rate of 90 Mbps in NRZ format, validated across all operating conditions (−40°C to +105°C) and supply configurations (3.3 V, 5 V, or mixed). This performance is specified for the C-grade version and enables use in high-speed serial interfaces such as isolated SPI clock lines and motor encoder feedback channels.
Does ADUM4401ARWZ support level translation between 3.3 V and 5 V domains?
Yes, ADUM4401ARWZ supports true bidirectional level translation: Side 1 can operate at 3.0–5.5 V independently from Side 2 (also 3.0–5.5 V). This allows direct interfacing between a 3.3 V microcontroller and a 5 V gate driver or industrial I/O circuit without external level-shifting components.
What safety certifications apply to ADUM4401ARWZ?
ADUM4401ARWZ holds UL 1577 (5000 VRMS), DIN EN IEC 60747-17 (VDE 0884-17, VIORM = 645 VPEAK), IEC 60601-1 (2 MOPP), IEC 62368-1, and CQC GB 4943.1 approvals - all verified for the RW-16 package variant. These certifications cover reinforced insulation for medical, industrial, and consumer safety-critical applications.
How does the output enable function work on ADUM4401ARWZ?
ADUM4401ARWZ features two independent output enable pins: VE1 (pin 7) controls Side 1 outputs (VOD), and VE2 (pin 10) controls Side 2 outputs (VOA–VOC). Both are active-high; pulling either low places its respective outputs in high-impedance state within 8 ns, enabling safe power sequencing and fault isolation without signal contention.
What is the pulse width distortion specification for ADUM4401ARWZ?
ADUM4401ARWZ has a maximum pulse width distortion (PWD) of 2 ns for the C-grade version - defined as |tPLH − tPHL| - ensuring minimal duty-cycle degradation in PWM transmission. This spec is guaranteed over temperature (−40°C to +105°C) and supply voltage (3.0–5.5 V), critical for accurate motor phase timing and isolated feedback loops.
