Product details
Overview
ADUM2401ARIZ-RL from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation technology, providing bidirectional signal transmission across a reinforced 5000 Vrms isolation barrier. It supports 3 V/5 V level translation, operates up to 90 Mbps (CRWZ grade), delivers <2 ns pulse width distortion and <2 ns channel-to-channel matching, and is used in motor drive gate driver interfaces requiring high common-mode transient immunity (>25 kV/µs).
For engineers reviewing the ADUM2401ARIZ-RL datasheet, ADUM2401ARIZ-RL pinout, ADUM2401ARIZ-RL application, or ADUM2401ARIZ-RL equivalent, this page provides verified specifications, SOIC-16 wide-body package details, functional channel configuration (3 forward + 1 reverse), safety certifications (UL, VDE, IEC 62368-1), and validated alternative options for industrial isolation design.
Technical Context
The ADUM2401ARIZ-RL implements four independent isolation channels with asymmetric directionality: three channels (A, B, C) transmit from side 1 to side 2, while one channel (D) transmits from side 2 to side 1. It uses monolithic air-core transformers instead of optocouplers, eliminating CTR drift and lifetime degradation.
Its dual-supply architecture allows VDD1 and VDD2 to operate independently between 2.7 V and 5.5 V, enabling true 3 V/5 V level translation across the barrier. A patented refresh circuit ensures DC correctness during idle periods and power transitions without external supervision.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8641ED-B-IS | Capacitive isolation; 100 Mbps max; 3.75 kVrms isolation rating; no integrated refresh circuit | Lacks reinforced insulation certification (UL 60601-1, IEC 62368-1) required for medical/industrial safety-critical use | Choose when cost sensitivity outweighs regulatory compliance and DC correctness requirements |
| ISO6741-Q1 | Capacitive isolation; 50 Mbps max; AEC-Q100 qualified; 5000 Vrms rating; 1 forward + 3 reverse channel config | Reverse-biased channel allocation mismatches ADUM2401ARIZ-RL's 3F+1R topology; unsuitable for gate-driver feedback architectures | Prefer only in automotive contexts where AEC-Q100 is mandatory and channel direction aligns with system layout |
Compared with SI8641ED-B-IS and ISO6741-Q1, ADUM2401ARIZ-RL uniquely combines reinforced 5000 Vrms certification, 3F+1R channel mapping, and guaranteed DC correctness-making it the only option qualified for safety-critical industrial motor drives and medical power supplies requiring long-term reliability without refresh overhead.

FAQ
What is the isolation voltage rating of ADUM2401ARIZ-RL and which standards does it meet?
ADUM2401ARIZ-RL is rated for 5000 Vrms isolation for 1 minute per UL 1577 and has a maximum repetitive peak isolation voltage (VIORM) of 645 Vpeak per DIN EN IEC 60747-17 (VDE 0884-17). It is certified to IEC/EN/CSA 62368-1, IEC/CSA 60601-1, and IEC/CSA 61010-1, making it suitable for reinforced insulation in medical and industrial equipment.
How does the channel directionality of ADUM2401ARIZ-RL differ from ADUM2400 and ADUM2402?
ADUM2401ARIZ-RL features three forward-direction channels (A–C, side 1 → side 2) and one reverse-direction channel (D, side 2 → side 1). This differs from ADUM2400 (all four forward) and ADUM2402 (two forward, two reverse), making ADUM2401ARIZ-RL optimal for asymmetric interfaces like motor gate drivers with three control signals and one fault feedback line.
Does ADUM2401ARIZ-RL require an external refresh signal or clock to maintain DC correctness?
No. ADUM2401ARIZ-RL incorporates a patented internal refresh circuit that automatically maintains DC-correct output states during static input conditions and across power-up/power-down sequences. No external components, clocks, or host intervention are needed - a key differentiator from competing isolators lacking this feature.
Can ADUM2401ARIZ-RL operate with different supply voltages on each side (e.g., 3.3 V on side 1 and 5 V on side 2)?
Yes. ADUM2401ARIZ-RL supports mixed-supply operation: VDD1 and VDD2 can each range from 2.7 V to 5.5 V independently. In 3.3 V/5 V mode, it provides true level translation - accepting 3.3 V logic on side 1 and delivering 5 V-compatible outputs on side 2, or vice versa, without external level shifters.
What is the maximum data rate supported by ADUM2401ARIZ-RL and under what conditions is it guaranteed?
ADUM2401ARIZ-RL supports up to 90 Mbps (NRZ) at 25°C with CL = 15 pF and CMOS signal levels - guaranteed for the CRWZ speed grade. Pulse width distortion remains ≤2 ns at this rate, ensuring reliable high-speed SPI, digital encoder, and PWM signal isolation in demanding real-time control systems.
