Product details
Overview
ADUM4400ARWZ-RL from Analog Devices is a 5 kVRMS quad-channel digital isolator using iCoupler® transformer-based technology, providing bidirectional signal isolation across two independent voltage domains. It supports 3.3 V/5 V level translation, operates up to 90 Mbps (NRZ), delivers ≤2 ns pulse width distortion and ≤2 ns channel-to-channel matching, and is widely deployed in medical equipment power supply control interfaces.
For engineers reviewing the ADUM4400ARWZ-RL datasheet, ADUM4400ARWZ-RL pinout, ADUM4400ARWZ-RL application, or ADUM4400ARWZ-RL equivalent, this page provides verified specifications, safety-certified insulation parameters, SOIC-Wide (RW-16) package details, and validated alternative options for high-reliability isolated communication design.
Technical Context
The ADUM4400ARWZ-RL implements four unidirectional, input-side-driven channels with output enable (VE2) on Side 2 only. Its monolithic air-core transformer architecture enables dc-correct operation via patented refresh circuitry during power-up and idle periods, eliminating optocoupler aging and timing drift.
It achieves reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17), with VIORM = 645 Vpeak, VIOWM = 456 Vrms, and certified 5000 Vrms/1 min withstand voltage - validated for IEC 60601-1 (2 MOPP), IEC 62368-1, and IEC 61010-1 compliance in medical and industrial systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 90 Mbps NRZ - supports high-speed serial links including SPI clock/data lines and isolated UARTs without external timing constraints. |
| Isolation Rating | 5000 VRMS/1 min - meets UL 1577 and enables safe separation between patient-connected circuits and mains-referenced logic in Class II medical devices. |
| Pulse Width Distortion | ≤2 ns max - ensures accurate duty-cycle preservation for PWM signals in motor drive gate driver feedback loops. |
| Common-Mode Transient Immunity | >25 kV/µs - maintains signal integrity during fast-switching events in inverters and SMPS where ground bounce exceeds 1 kV/µs. |
| Supply Range | 3.0 V to 5.5 V per side - allows mixed-voltage system interfacing (e.g., 3.3 V MCU to 5 V PLC I/O) without level-shifter ICs. |
| Propagation Delay Skew | ≤2 ns (C grade) - guarantees synchronized sampling across all four channels for time-critical ADC/DAC isolation in data acquisition systems. |
| Output Enable Function | VE2 active-high on Side 2 - enables centralized bus contention control and low-power sleep mode by placing outputs in high-Z state. |
Pinout & Package
ADUM4400ARWZ-RL uses a 16-lead SOIC wide-body (RW-16) package with 7.8 mm minimum creepage/clearance, optimized for reinforced insulation in pollution degree 2 environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | VDD1 / VDD2 | Independent 3.0–5.5 V supplies for isolated input/output sides - enables asymmetric rail operation (e.g., 5 V primary, 3.3 V secondary). |
| 2, 8, 9, 15 | GND1 / GND2 | Dedicated ground planes per side - prevents noise coupling; requires separate PCB ground pours with no direct trace connection across isolation barrier. |
| 3–6 | VIA–VID | Four logic inputs on Side 1 - accepts CMOS/TTL levels; VIH = 2.0 V (5 V mode), VIH = 1.6 V (3.3 V mode). |
| 10 | VE2 | Active-high output enable for Side 2 - drives all VOx pins into high-impedance when low; critical for shared-bus arbitration. |
| 11–14 | VOD–VOA | Four buffered CMOS outputs on Side 2 - VOH ≥ VDD2 − 0.4 V @ 3.2 mA, VOL ≤ 0.4 V @ 3.2 mA - directly drives standard logic loads. |
| 7 | NC | No internal connection - must remain unconnected; no routing or thermal pad required. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Insulation Certification | DIN EN IEC 60747-17 (VDE 0884-17), UL 1577, IEC 60601-1 (2 MOPP), IEC 62368-1 - eliminates need for external safety capacitors or creepage extenders in certified designs. |
| Low-Power Operation | 1.4 mA/channel @ 2 Mbps (5 V), 0.9 mA/channel @ 2 Mbps (3.3 V) - reduces thermal load in sealed enclosures and extends battery life in portable medical monitors. |
| High-Temperature Reliability | Rated for continuous operation at TA = −40°C to +105°C - supports placement near power stages in motor drives and industrial inverters without derating. |
| Input Glitch Filter | Integrated noise suppression on all inputs - rejects sub-10 ns transients common in noisy factory-floor environments without external RC filters. |
| DC-Correct Refresh Logic | Patented internal refresh at 1.2 Mbps - guarantees output state retention during static input conditions or brown-out events, eliminating hold-time failures. |

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; 150 Mbps max; no output enable pin; 2.5 V–5.5 V supply. | Lacks VE2 control; higher speed but less deterministic propagation delay (±5 ns vs. ±2 ns); no IEC 60601-1 certification. | Prefer ADUM4400ARWZ-RL for medical systems requiring 2 MOPP and precise timing; SI8440AB-B-IS suits cost-sensitive industrial comms where speed >90 Mbps is needed. |
| ISO6741QDWR | Capacitive isolation; 5 kVRMS; 50 Mbps max; integrated 3.3 V LDO on Side 2; no output enable. | Includes regulated output supply but sacrifices speed and lacks VE2; certified to IEC 60601-1 but only 1 MOPP. | Choose ADUM4400ARWZ-RL when independent dual supplies and bus arbitration are required; ISO6741QDWR fits space-constrained designs needing integrated regulation. |
Compared with SI8440AB-B-IS and ISO6741QDWR, ADUM4400ARWZ-RL uniquely combines 2 MOPP medical certification, output enable functionality, and sub-2 ns timing precision - making it the only option among the three qualified for safety-critical, time-synchronized isolation in Class II medical equipment.

FAQ
What is the maximum data rate supported by ADUM4400ARWZ-RL?
ADUM4400ARWZ-RL 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). This rating applies to the C-grade version specified in the Rev. G datasheet and is guaranteed with ≤2 ns pulse width distortion and ≤2 ns channel-to-channel skew.
Does ADUM4400ARWZ-RL support level translation between 3.3 V and 5 V domains?
Yes, ADUM4400ARWZ-RL supports true bidirectional level translation: Side 1 (VDD1) and Side 2 (VDD2) operate independently from 3.0 V to 5.5 V. When VDD1 = 5 V and VDD2 = 3.3 V, inputs accept 5 V logic thresholds while outputs drive 3.3 V compatible levels - enabling seamless interface between legacy 5 V controllers and modern 3.3 V peripherals without external translators.
What safety certifications does ADUM4400ARWZ-RL hold?
ADUM4400ARWZ-RL holds UL 1577 (5000 VRMS/1 min), DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation, IEC 60601-1 (2 MOPP), IEC 62368-1, and IEC 61010-1. These certifications are specific to the RW-16 package variant and are documented in Table 14 of the Rev. G datasheet.
How does the output enable (VE2) pin function on ADUM4400ARWZ-RL?
The VE2 pin on ADUM4400ARWZ-RL is an active-high enable for all four Side 2 outputs (VOA–VOD). When VE2 is high or left floating, outputs reflect input states; when VE2 is low, all VOx pins enter high-impedance state. Propagation delay from VE2 transition to output disable/enable is ≤8 ns, enabling precise bus arbitration in multi-master systems.
What is the common-mode transient immunity (CMTI) specification for ADUM4400ARWZ-RL?
ADUM4400ARWZ-RL has a minimum common-mode transient immunity of 25 kV/µs, tested per IEC 61000-4-x standards with VCM = 1000 V and transient magnitude = 800 V. This performance is maintained across temperature (−40°C to +105°C) and supply voltages (3.0–5.5 V), ensuring reliable operation in high-noise motor drive and SMPS environments.
