Product details
Overview
ADUM3401WARWZ from Analog Devices is a quad-channel, reinforced digital isolator based on iCoupler® transformer technology, providing bidirectional signal isolation with 560 VPEAK working voltage, 10 Mbps data rate, and 25 kV/µs common-mode transient immunity. It supports 3.135 V to 5.5 V dual-supply operation (VDD1/VDD2), enables 3.3 V/5 V level translation, and features output enable (VE1/VE2) for channel control in motor drive and battery monitor systems.
For engineers reviewing the ADUM3401WARWZ datasheet, ADUM3401WARWZ pinout, ADUM3401WARWZ application, or ADUM3401WARWZ equivalent, this page delivers verified specifications including propagation delay skew ≤3.5 ns, pulse width distortion ≤3.5 ns, quiescent supply current as low as 0.31 mA per channel at 3.3 V, and UL/VDE-reinforced insulation compliance - all critical for automotive-grade isolated communication design.
Technical Context
The ADUM3401WARWZ implements four independent unidirectional channels (A/B inputs → A/B outputs; C/D inputs ← C/D outputs), with dedicated output enable pins VE1 (Pin 7) and VE2 (Pin 10) controlling side-1 and side-2 outputs respectively. Its monolithic air-core transformer architecture eliminates optocoupler limitations like CTR drift and aging, while integrated refresh circuitry ensures DC correctness during power-up, power-down, and idle states.
It operates across −40°C to +125°C with guaranteed performance under mixed-voltage conditions (e.g., 5 V side-1 / 3.3 V side-2), delivering precise timing: max 3.5 ns pulse width distortion and 3.5 ns codirectional channel-to-channel matching. Safety certification includes UL 2500 VRMS/1 min, VDE V 0884-10 reinforced insulation (VIORM = 560 VPEAK), and CSA Component Acceptance Notice #5A.

Pinout & Package
ADUM3401WARWZ uses a 16-lead SOIC wide-body (RW-16) RoHS-compliant package with 7.7 mm minimum creepage/clearance. Pin 2 and Pin 8 are internally connected GND1; Pin 9 and Pin 15 are internally connected GND2. VE1 (Pin 7) and VE2 (Pin 10) provide independent output enable control per side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 (Pin 1) | Side-1 primary supply | 3.135–5.5 V input-side power; powers VIA/VIB/VE1 logic and transformers. |
| GND1 (Pins 2, 8) | Side-1 reference ground | Internally tied; dual connection improves noise rejection and thermal dissipation. |
| VIA, VIB (Pins 3, 4) | Input channels A and B | Unidirectional logic inputs referenced to VDD1/GND1; compatible with CMOS/LVTTL. |
| VE1 (Pin 7) | Side-1 output enable | Active-high control for VOA/VOB outputs; low state places outputs in high-impedance mode. |
| VDD2 (Pin 16) | Side-2 secondary supply | 3.135–5.5 V output-side power; powers VOC/VOD/VE2 logic and transformer secondaries. |
| GND2 (Pins 9, 15) | Side-2 reference ground | Internally tied; dual connection reduces ground bounce in high-current motor control circuits. |
| VOA, VOB (Pins 14, 13) | Output channels A and B | Unidirectional logic outputs referenced to VDD2/GND2; drive 4 mA loads at VOL ≤ 0.4 V. |
| VE2 (Pin 10) | Side-2 output enable | Active-high control for VOC/VOD outputs; enables independent shutdown of isolated sensor interface channels. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8641ED-B-IS | Capacitive isolation; 5000 VRMS rating; 150 kV/µs CMTI; no output enable pins. | Lacks per-side output enable; higher CMTI suits ultra-noisy RF environments but requires external level shifters for mixed-voltage use. | Prefer when maximum noise immunity is prioritized over flexible power gating. |
| ISO6741QDWR | Capacitive isolation; 5000 VRMS; 100 kV/µs CMTI; 3.3 V only; integrated LDO on side-2. | Single-supply operation simplifies BOM but limits level translation capability; not rated for 125°C ambient. | Select for cost-sensitive, non-automotive designs where side-2 voltage regulation is needed. |
Compared with SI8641ED-B-IS and ISO6741QDWR, ADUM3401WARWZ uniquely combines reinforced 560 VPEAK isolation, dual-output-enable control, and guaranteed 125°C operation - making it the only option qualified for ASIL-B automotive motor control and battery monitoring without derating.

FAQ
What is the maximum data rate supported by ADUM3401WARWZ?
ADUM3401WARWZ supports a maximum data rate of 10 Mbps in NRZ format, tested under CL = 15 pF load with CMOS signal levels. This performance is guaranteed across the full operating temperature range (−40°C to +125°C) and supply voltage range (3.135 V to 5.5 V). The 10 Mbps capability enables reliable isolation of high-speed interfaces such as SPI clock lines and fast UART links in ADUM3401WARWZ-based designs.
Does ADUM3401WARWZ support level translation between 3.3 V and 5 V domains?
Yes, ADUM3401WARWZ supports bidirectional level translation: it operates with VDD1 and VDD2 independently set from 3.135 V to 5.5 V, allowing configurations such as 5 V on side-1 and 3.3 V on side-2 (or vice versa). Input thresholds scale with respective supplies (VIH = 2.0 V at 5 V, 1.6 V at 3.3 V), and output drive strength is specified for both voltages - eliminating external level shifters in ADUM3401WARWZ implementations.
What safety certifications does ADUM3401WARWZ hold?
ADUM3401WARWZ is certified for reinforced isolation per UL 1577 (2500 VRMS/1 min), VDE V 0884-10 (VIORM = 560 VPEAK), and CSA Component Acceptance Notice #5A. It meets basic insulation requirements per IEC 60950-1 and is qualified for automotive applications. These approvals are production-tested on 100% of units, with partial discharge detection <5 pC during VDE qualification - confirming reliability in ADUM3401WARWZ safety-critical deployments.
How does the output enable function work on ADUM3401WARWZ?
ADUM3401WARWZ provides two independent output enable pins: VE1 (Pin 7) controls VOA/VOB outputs on side-1, and VE2 (Pin 10) controls VOC/VOD outputs on side-2. When asserted high (or left floating), outputs drive normally; when pulled low, outputs enter high-impedance state within 8 ns. This allows selective channel shutdown in ADUM3401WARWZ systems to reduce power or isolate faulted sections without resetting the entire isolator.
What is the pulse width distortion specification for ADUM3401WARWZ?
ADUM3401WARWZ has a maximum pulse width distortion (PWD) of 3.5 ns, defined as |tPLH − tPHL|, measured at 50% input/output thresholds under 3.3 V or 5 V operation. This tight PWD ensures minimal duty cycle degradation for PWM signals crossing the isolation barrier - a critical parameter for ADUM3401WARWZ use in gate driver interfaces where distorted pulses could cause shoot-through or reduced efficiency.
