Overview
ADUM4402ARWZ 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 insulation for high-voltage system separation in motor drives and medical equipment.
For engineers reviewing the ADUM4402ARWZ datasheet, ADUM4402ARWZ pinout, ADUM4402ARWZ application, or ADUM4402ARWZ equivalent, this page delivers verified specifications, safety-certified isolation parameters, channel-level power consumption at multiple data rates, and real-world design implications of its output enable function and mixed-supply operation.
Technical Context
The ADUM4402ARWZ implements iCoupler® monolithic air-core transformer technology across four independent channels, enabling galvanic isolation without optocoupler aging or LED drive complexity. Its architecture supports asymmetric supply configurations (e.g., 5 V on Side 1, 3.3 V on Side 2) while maintaining dc-correct output via patented refresh circuitry during power transitions.
It features dual output enable inputs (VE1 and VE2), allowing independent tri-state control of each side's outputs. The device meets DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation with VIORM = 645 Vpeak, and achieves >25 kV/µs common-mode transient immunity through optimized layout and internal filtering.
Key Specifications

|---|---|
| Data Rate | DC to 90 Mbps (NRZ); enables high-speed serial bus isolation such as SPI clock lines or encoder 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/CSA 60601-1 (2 MOPP). |
| Pulse Width Distortion | ≤2 ns (C grade); ensures minimal duty-cycle error in PWM signal isolation for gate drivers or analog-to-digital timing paths. |
| Supply Range | 3.0 V to 5.5 V per side; supports mixed-voltage systems (e.g., 3.3 V MCU side, 5 V sensor side) with automatic level translation. |
| Power @ 10 Mbps | 7.5 mA per side (3.3 V operation); enables low-power isolated communication in battery-backed or energy-sensitive industrial nodes. |
| Common-Mode Immunity | >25 kV/µs; maintains signal integrity in noisy motor drive or power supply environments with fast-switching transients. |
| Propagation Delay Skew | ≤5 ns (C grade); guarantees tight timing alignment across all four channels for synchronized control signals. |
Pinout & Package
ADUM4402ARWZ uses a 16-lead SOIC wide-body package (RW-16) with 7.8 mm creepage and clearance, rated for reinforced insulation per IEC 60747-17.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | VDD1 / VDD2 | Independent 3.0–5.5 V supplies for input and output sides; enables voltage translation and fault-isolated power domains. |
| 2, 8, 9, 15 | GND1 / GND2 | Separate ground references per isolation side; mandatory for noise-free signal transfer and safety compliance. |
| 3–6 | VIA–VID | Unidirectional logic inputs on Side 1; accept CMOS levels and support 0–90 Mbps operation with internal glitch filtering. |
| 10, 7 | VE2 / VE1 | Active-high output enable controls for Side 2 and Side 1 outputs respectively; allows dynamic channel disabling without PCB redesign. |
| 11–14 | VOD–VOA | Unidirectional logic outputs on Side 2; drive 3.2 mA loads with rail-to-rail swing and <8 ns enable/disable propagation delay. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Channel Configuration | ADUM4402ARWZ has two input-only channels (Side 1) and two output-only channels (Side 2), enabling asymmetric signal flow for control-to-peripheral isolation. |
| Output Enable Function | Dual independent enables (VE1/VE2) allow selective tri-stating of either side's outputs-critical for bus arbitration and hot-swap compatibility. |
| DC-Correct Refresh Logic | Patented refresh ensures output state retention during prolonged input inactivity or power-up/power-down sequences, eliminating external watchdog requirements. |
| Mixed-Supply Operation | Valid operation with VDD1 = 3.3 V / VDD2 = 5 V or vice versa; eliminates level-shifter ICs in heterogeneous voltage domain interfaces. |
| System-Level ESD Hardening | Enhanced layout and circuit design meet IEC 61000-4-x standards for ESD, EFT, and surge-reducing need for external protection components. |

FAQ
What is the maximum data rate supported by ADUM4402ARWZ?
ADUM4402ARWZ supports up to 90 Mbps in NRZ format under C-grade conditions. This maximum rate assumes proper termination, 15 pF load, and operation within recommended supply (3.0–5.5 V) and temperature (−40°C to +105°C) ranges. At lower speeds (e.g., 10 Mbps), ADUM4402ARWZ consumes significantly less power-7.5 mA per side at 3.3 V-making it suitable for both high-speed and low-power applications.
Does ADUM4402ARWZ support mixed-voltage operation between input and output sides?
Yes, ADUM4402ARWZ fully supports mixed-supply operation: VDD1 can be 3.3 V while VDD2 is 5 V, or vice versa. This enables direct level translation without external components. Electrical characteristics-including propagation delay, PWD, and supply current-are specified across all combinations in the datasheet (Tables 7 and 10), confirming robust functionality in heterogeneous voltage domain interfaces.
What safety certifications apply to ADUM4402ARWZ?
ADUM4402ARWZ holds UL 1577 (5000 VRMS), 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 VIORM = 645 Vpeak and reinforced insulation construction make it suitable for Class II medical devices and industrial equipment requiring dual protection means.
How does the output enable function work on ADUM4402ARWZ?
ADUM4402ARWZ features two independent output enable inputs: VE1 controls Side 1 outputs (VOA–VOD), and VE2 controls Side 2 outputs (VOA–VOD). When asserted high (or left floating), outputs drive normally; when pulled low, they enter high-impedance state within 8 ns. This allows dynamic bus sharing and hot-swap capability without affecting isolated power domains.
What is the common-mode transient immunity (CMTI) specification for ADUM4402ARWZ?
ADUM4402ARWZ delivers >25 kV/µs common-mode transient immunity, tested per IEC 61000-4-4 with 800 V transient magnitude at 1000 V common-mode bias. This performance is achieved through proprietary transformer layout and internal filtering, ensuring reliable operation in high-noise environments like variable-frequency drives and switch-mode power supplies where fast dV/dt events occur across the isolation barrier.
