Product details
Overview
ADUM226N0WBRIZ from Analog Devices is a dual-channel, 5.0 kVrms reinforced digital isolator in a 16-lead SOIC_W (RW-16) package, supporting 1.8 V to 5 V level translation across the isolation barrier, with 150 Mbps data rate and 13 ns max propagation delay at 5 V - deployed in automotive battery management systems for CAN/UART signal isolation.
For engineers reviewing the ADUM226N0WBRIZ datasheet, ADUM226N0WBRIZ pinout, ADUM226N0WBRIZ application, or ADUM226N0WBRIZ equivalent, this page delivers verified specifications, fail-safe output behavior, regulatory compliance (UL 1577, VDE 0884-17, IEC 60601-1), and real-world design context for high-noise industrial and automotive isolation interfaces.
Technical Context
The ADUM226N0WBRIZ implements iCoupler® technology using monolithic air-core transformers, eliminating LED aging and timing drift inherent in optocouplers. Its two independent unidirectional channels support asymmetric supply configurations (e.g., 1.8 V on side 1, 5 V on side 2), enabling voltage-level translation without external level shifters.
It features fail-safe high output logic state when input power is absent, meets reinforced insulation requirements per DIN EN IEC 60747-17 (VIORM = 849 Vpeak), and sustains 100 kV/µs common-mode transient immunity - critical for motor drive gate driver feedback and isolated ADC interfaces in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 150 Mbps - supports high-speed serial protocols including isolated CAN FD and SPI clock domains. |
| Propagation Delay | 13 ns max at 5 V - enables tight timing control in real-time control loops and fast-response safety monitoring. |
| Isolation Voltage | 5.0 kVrms for 1 minute - certified for reinforced insulation in medical (IEC 60601-1) and industrial (IEC 62368-1) applications. |
| Common-Mode Immunity | 100 kV/µs - maintains signal integrity during fast transients in motor drives and HV battery monitoring. |
| Supply Range | 1.8 V to 5 V per side - allows direct interfacing with low-voltage MCUs and legacy 5 V peripherals across isolation barrier. |
| Fail-Safe Output | High-state default on power loss - ensures defined logic level in fault conditions for safety-critical enable/disable signals. |
| Operating Temperature | −40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood automotive use. |
Pinout & Package
ADUM226N0WBRIZ uses a 16-lead SOIC_W (RW-16) package with 7.81 mm minimum creepage/clearance, optimized for reinforced insulation in high-voltage systems. Pin 1–8 form the input-side terminal group; pins 9–16 form the output-side group.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, Pin 1 | Input-side supply | Power for channel A/B inputs; supports 1.8–5 V; UVLO threshold 1.6 V. |
| GND1, Pin 2 | Input-side ground | Reference return for input logic and supply; must be isolated from GND2. |
| INA, Pin 3 | Channel A input | CMOS-compatible digital input; VIH = 0.7×VDD1, VIL = 0.3×VDD1. |
| INB, Pin 4 | Channel B input | Independent second input; identical electrical specs to INA. |
| VDD2, Pin 10 | Output-side supply | Power for channel A/B outputs; independent voltage domain (1.8–5 V). |
| GND2, Pin 11 | Output-side ground | Reference return for outputs; galvanically separated from GND1. |
| OUTA, Pin 12 | Channel A output | Fail-safe high on VDD1 loss; VOH ≥ VDD2 − 0.4 V @ 4 mA load. |
| OUTB, Pin 13 | Channel B output | Same fail-safe behavior as OUTA; supports independent logic thresholds. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8621ED-B-IS | 3.75 kVrms isolation; 100 Mbps; SOIC-8 package; no AEC-Q100 qualification | Limited to non-automotive industrial use; lower creepage (5.5 mm) restricts high-voltage designs | Choose for cost-sensitive, space-constrained 3.3 V systems where 5 kVrms and automotive grade are not required. |
| ISO7721DWR | 5.0 kVrms; 100 Mbps; SOIC-8; fails low on input power loss; TI's capacitive isolation | Fail-low behavior conflicts with ADUM226N0WBRIZ's fail-high requirement in safety-enable paths | Select only if system architecture mandates low-state default and layout constraints prohibit 16-pin SOIC_W. |
Compared with SI8621ED-B-IS and ISO7721DWR, ADUM226N0WBRIZ uniquely combines AEC-Q100 Grade 1 qualification, 150 Mbps speed, fail-high safety logic, and 7.81 mm creepage - making it the only option qualified for reinforced isolation in automotive BMS and high-CMTI industrial inverters.

FAQ
What is the fail-safe output behavior of ADUM226N0WBRIZ?
The ADUM226N0WBRIZ features a fail-safe high output state: when VDD1 is unpowered or disabled, both OUTA and OUTB drive logic high. This behavior is confirmed in the datasheet truth table and ensures defined signaling in power-loss scenarios - critical for safety interlocks in automotive and industrial systems using ADUM226N0WBRIZ.
Does ADUM226N0WBRIZ support bidirectional communication?
No, ADUM226N0WBRIZ provides two independent unidirectional channels (INA→OUTA, INB→OUTB). It does not support true bidirectional data flow on a single pin pair. For bidirectional isolation, separate transmit/receive pairs or dedicated bidirectional isolators like ADUM1280 must be used - ADUM226N0WBRIZ is designed strictly for point-to-point unidirectional signal transfer.
What safety certifications apply to ADUM226N0WBRIZ?
ADUM226N0WBRIZ is certified to UL 1577 (5000 Vrms, 1 min), DIN EN IEC 60747-17 (VDE 0884-17, VIORM = 849 Vpeak), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1. These approvals are explicitly listed in Tables 13 and 14 of the Rev. D datasheet for the ADuM226N family.
Can ADUM226N0WBRIZ operate with different supply voltages on each side?
Yes - ADUM226N0WBRIZ supports independent 1.8 V to 5 V supplies on VDD1 and VDD2, enabling level translation. For example, it can accept 1.8 V logic inputs while driving 3.3 V or 5 V outputs. This capability is specified across all operating conditions in Tables 1–7 of the datasheet and is fundamental to its role in mixed-voltage system isolation.
What is the maximum data rate guaranteed for ADUM226N0WBRIZ?
The ADUM226N0WBRIZ guarantees 150 Mbps operation under all specified conditions (−40°C to +125°C, 1.8–5 V supplies), as stated in the "Features" section and confirmed in Tables 1–7 under "Data Rate". This rate is maintained within pulse width distortion limits and applies to both channels simultaneously.
