Product details
Overview
ADuM4401ARIZ 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 for high-noise industrial interfaces.
For engineers reviewing the ADuM4401ARIZ datasheet, ADuM4401ARIZ pinout, ADuM4401ARIZ application, or ADuM4401ARIZ equivalent, this device supports safety-critical isolation in motor drives, medical equipment, and isolated power supply feedback loops where reinforced insulation (VIORM = 645 Vpeak) and precise timing (<2 ns channel matching) are required.
Technical Context
The ADuM4401ARIZ implements iCoupler® monolithic air-core transformer technology across four independent channels, enabling galvanic isolation without optocoupler aging or LED drive complexity. Its dual-supply architecture (VDD1/VDD2 = 3.0–5.5 V) supports asymmetric voltage operation (e.g., 5 V input / 3.3 V output) and integrated refresh circuitry ensures DC correctness during power-up and signal inactivity.
It features active output enable (VE1 on Side 1, VE2 on Side 2), low-power dynamic current scaling (0.10–0.20 mA/Mbps), and patented layout enhancements for system-level IEC 61000-4-x ESD/burst/surge compliance. Channel configuration is 2-input/2-output per side with dedicated enable control per side.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 90 Mbps (NRZ) - supports high-speed SPI, RS-485, and gate driver interface timing. |
| Isolation Rating | 5000 VRMS for 1 minute - certified for reinforced insulation per UL 1577, IEC/EN/CSA 62368-1, and DIN EN IEC 60747-17 (VDE 0884-17). |
| Pulse Width Distortion | ≤2 ns maximum - ensures minimal duty-cycle error in PWM and clock transmission applications. |
| Channel Matching | ≤2 ns maximum - guarantees tight skew between parallel isolated signals (e.g., encoder A/B lines). |
| Common-Mode Immunity | >25 kV/µs - maintains signal integrity in high-dv/dt environments like IGBT gate driving and motor phase sensing. |
| Supply Current @ 10 Mbps | 10.6 mA (Side 1) / 3.3 mA (Side 2) at 3.3 V - enables low-power isolated communication in battery-backed or energy-sensitive systems. |
| Operating Temperature | −40°C to +105°C - suitable for under-hood automotive, industrial PLC, and medical power supply environments. |
Pinout & Package
ADuM4401ARIZ uses a 16-lead SOIC wide-body package (RI-16) with enhanced creepage (8.7 mm clearance/creepage), 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 isolated input/output sides - enables level translation and fault-isolated power domains. |
| 2, 8, 9, 15 | GND1 / GND2 | Dedicated ground references per side - prevents ground loop coupling and preserves CMRR. |
| 3–5, 11 | VIA–VIC, VOD | Three input pins (Side 1) and one output pin (Side 2) - defines 3:1 unidirectional channel split (A/B/C → D). |
| 6, 12–14 | VOD, VOC–VOA | One input (Side 2) and three outputs (Side 1) - completes bidirectional 4-channel mapping with side-specific directionality. |
| 7, 10 | VE1 / VE2 | Active-high output enable per side - allows dynamic tri-state control of isolated outputs for bus sharing or power sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional 4-channel isolation | Configurable as 3 inputs + 1 output on Side 1 and 1 input + 3 outputs on Side 2 - supports asymmetric protocol stacks (e.g., isolated ADC readback + DAC write). |
| Reinforced insulation certification | VIORM = 645 Vpeak, VIOWM = 456 Vrms, and 10,000 Vpeak surge rating - meets 2 MOPP requirements for IEC 60601-1 medical equipment. |
| Low-power mixed-voltage operation | 0.10 mA/Mbps dynamic current scaling at 3.3 V - reduces thermal load in compact isolated DC-DC feedback paths. |
| Integrated DC-correctness refresh | 1.2 Mbps refresh rate - eliminates output latch-up during idle periods or slow-changing logic states without external watchdog circuitry. |
| Noise-immune output enable | VE1/VE2 accept NC or logic-high for default-enable; logic-low forces high-impedance - prevents spurious output activation in ESD-prone environments. |
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 |
|---|---|---|---|
| Si8440AB-B-IS | 4-channel, 1 Mbps max, 3.75 kVRMS isolation, no output enable, 16-pin SOIC narrow body | Lacks VE1/VE2 control and reinforced insulation rating - unsuitable for medical 2 MOPP or high-CMTI motor drives | Select only for cost-sensitive, low-speed, non-safety-critical isolation where board space is constrained. |
| ISO6741QDWR | 4-channel, 50 Mbps max, 5 kVRMS, 16-pin SOIC wide, no side-specific enable (global OE) | Lower data rate limits use in high-frequency PWM; single OE pin reduces flexibility in asymmetric protocols | Prefer when TI ecosystem compatibility or AEC-Q100 qualification is required, but verify timing margins at 50 Mbps. |
Compared with Si8440AB-B-IS and ISO6741QDWR, ADuM4401ARIZ uniquely combines 90 Mbps speed, side-specific output enable, and certified 2 MOPP reinforcement - making it the only option among the three qualified for high-fidelity isolated data acquisition in Class III medical devices.

FAQ
What is the maximum data rate supported by ADuM4401ARIZ?
ADuM4401ARIZ supports a maximum data rate of 90 Mbps in NRZ format, verified across all operating conditions (−40°C to +105°C, 3.0–5.5 V supplies). This performance is guaranteed for C-grade devices and enables high-speed isolated communication for SPI, digital encoder interfaces, and gate driver timing signals without compromising pulse width distortion (<2 ns).
Does ADuM4401ARIZ support mixed-voltage operation between input and output sides?
Yes, ADuM4401ARIZ fully supports mixed-voltage operation: VDD1 and VDD2 can be independently set to 3.3 V or 5 V (within 3.0–5.5 V range), enabling seamless 3.3 V ↔ 5 V level translation across the isolation barrier. Electrical characteristics-including propagation delay and supply current-are specified for all combinations (5 V/3.3 V and 3.3 V/5 V) in the datasheet Rev. G.
What safety certifications apply to ADuM4401ARIZ?
ADuM4401ARIZ 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. The RI-16 package is specifically certified for reinforced insulation with VIORM = 645 Vpeak and 8.7 mm creepage/clearance.
How does the output enable (VE1/VE2) function in ADuM4401ARIZ?
ADuM4401ARIZ features two independent output enable pins: VE1 controls Side 1 outputs (VOA–VOC), and VE2 controls Side 2 outputs (VOD). Both are active-high; when asserted, outputs drive logic levels; when low, outputs enter high-impedance state. This allows dynamic bus sharing, power sequencing, and noise-immune control-critical in multi-master isolated networks.
What is the common-mode transient immunity (CMTI) specification for ADuM4401ARIZ?
ADuM4401ARIZ guarantees >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 high CMTI ensures reliable operation in noisy environments such as IGBT-based motor drives and switch-mode power supplies where rapid voltage transients cross the isolation barrier.
