Product details
Overview
ADUM4401ARWZ-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 (3.0–5.5 V each). It delivers 90 Mbps data rate, <2 ns pulse width distortion, and 25 kV/µs common-mode transient immunity, enabling robust communication in high-noise industrial motor drives and medical equipment interfaces.
For engineers reviewing the ADUM4401ARWZ-RL datasheet, ADUM4401ARWZ-RL pinout, ADUM4401ARWZ-RL application, or ADUM4401ARWZ-RL equivalent, this page provides verified specifications, SOIC-W-16 pin mapping, safety-certified insulation parameters, and validated alternative options for high-reliability isolated I/O design.
Technical Context
The ADUM4401ARWZ-RL implements four independent unidirectional channels with side-specific output enable (VE1 on Side 1, VE2 on Side 2), supporting mixed-voltage operation (e.g., 5 V input / 3.3 V output). Its air-core transformer isolation eliminates LED aging and timing drift inherent in optocouplers.
It features patented refresh circuitry ensuring DC-correct output during power-up, power-down, or static input conditions, and includes input glitch filtering to suppress noise-induced false transitions-critical for PLC I/O and patient-connected medical systems.

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 | Capacitive isolation; 5 kVRMS; 100 Mbps; no output enable on Side 1 | Lacks VE1 pin - requires external logic for Side 1 output control in asymmetric designs | Prefer when maximum speed (100 Mbps) is critical and dual-side enable is unnecessary |
| ISO6741-Q1 | Capacitive isolation; AEC-Q100 Grade 1; 5000 VRMS; 50 Mbps; 3.0–5.5 V operation | Automotive-qualified but lower data rate - not suitable for 90 Mbps SPI or fast PWM | Select for automotive body electronics where AEC-Q100 compliance outweighs speed requirements |
Compared with SI8641ED-B-IS and ISO6741-Q1, ADUM4401ARWZ-RL uniquely provides dual output-enable pins (VE1/VE2), 90 Mbps capability, and proven iCoupler® magnetic immunity - making it optimal for industrial motion control where both speed and flexible channel control are essential.

FAQ
What is the maximum data rate supported by ADUM4401ARWZ-RL?
ADUM4401ARWZ-RL supports a maximum data rate of 90 Mbps in NRZ format. This specification applies to the C-grade version under recommended operating conditions (VDD = 3.3 V or 5 V, TA = −40°C to +105°C). At lower speeds (e.g., 10 Mbps), power consumption drops significantly - 4.3 mA/channel at 5 V - making it suitable for both high-speed and low-power implementations.
Does ADUM4401ARWZ-RL support mixed-voltage operation between input and output sides?
Yes, ADUM4401ARWZ-RL 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). For example, it operates reliably with 5 V on Side 1 and 3.3 V on Side 2, enabling seamless level translation in systems interfacing legacy 5 V peripherals with modern 3.3 V processors - confirmed in Tables 7 and 10 of the Rev. G datasheet.
What safety certifications does ADUM4401ARWZ-RL hold?
ADUM4401ARWZ-RL holds UL 1577 (5000 VRMS), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), IEC/CSA 61010-1, and DIN EN IEC 60747-17 (VDE 0884-17) approvals. Its RW-16 package achieves 645 VPEAK VIORM and 456 VRMS VIOWM, satisfying reinforced insulation requirements for medical and industrial end-equipment.
How does the output enable function work on ADUM4401ARWZ-RL?
ADUM4401ARWZ-RL features two independent output enable pins: 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 power sequencing - critical in multi-master SPI or shared I²C topologies.
What is the common-mode transient immunity (CMTI) of ADUM4401ARWZ-RL?
ADUM4401ARWZ-RL guarantees >25 kV/µs common-mode transient immunity, tested per IEC 61000-4-x with VCM = 1000 V and transient magnitude = 800 V. This performance is enabled by monolithic air-core transformer architecture and internal layout enhancements - exceeding typical optocoupler CMTI by 5× and preventing data corruption during fast-switching events in motor drives.
