Product details
Overview
ADUM241D0BRWZ-RL from Analog Devices is a quad-channel digital isolator based on iCoupler® technology, providing 5.0 kVrms reinforced insulation for high-noise industrial and medical systems. It delivers 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, and operates across 1.8 V to 5 V supply rails with level translation capability. Its fail-safe high output state supports SPI isolation in motor control gate drivers.
For engineers reviewing the ADUM241D0BRWZ-RL datasheet, ADUM241D0BRWZ-RL pinout, ADUM241D0BRWZ-RL application, or ADUM241D0BRWZ-RL equivalent, this page provides verified specifications, SOIC_W package details, safety certifications (UL 1577, VDE 0884-17), and real-world use cases in isolated SPI interfaces and IEC 60601-1 medical equipment.
Technical Context
The ADUM241D0BRWZ-RL implements four independent unidirectional channels with input-side power (VDD1) and output-side power (VDD2) operating independently from 1.8 V to 5 V. Its monolithic air-core transformer architecture ensures dc-correct output behavior without input transitions and supports fail-safe high output when input power is absent.
It achieves 100 kV/µs common-mode transient immunity with tight channel matching (≤3.0 ns), low jitter (70 ps rms), and pulse width distortion <3 ns - enabling reliable high-speed serial communication across reinforced isolation barriers in PLC backplanes and isolated ADC interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5.0 kVrms for 1 minute - meets reinforced insulation requirements per UL 1577 and IEC/EN 60747-17 (VDE 0884-17) |
| Max Data Rate | 150 Mbps - guarantees full-speed SPI, RS-485, and CAN FD signal integrity across isolation barrier |
| Propagation Delay | 13 ns max at 5 V - enables sub-20 ns round-trip latency for closed-loop feedback in servo drives |
| Supply Range | 1.8 V to 5 V on both sides - supports mixed-voltage system interfacing (e.g., 3.3 V MCU to 5 V sensor) |
| Common-Mode Immunity | 100 kV/µs - maintains signal integrity during fast transients in motor drive switching noise environments |
| Fail-Safe Output | High-state default - ensures defined logic level during power loss or disable, critical for safety shutdown circuits |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial ambient conditions |
Pinout & Package
ADUM241D0BRWZ-RL uses a 16-lead RoHS-compliant SOIC_W (RW-16) wide-body package with 7.8 mm creepage and clearance, optimized for reinforced insulation in high-voltage applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Input-side power supply | Supplies logic side (channels A–D inputs); accepts 1.8–5 V; powers internal input circuitry and transformers |
| GND1 | Input-side ground reference | Reference for VDD1 and all input signals; must be separated from GND2 by ≥7.8 mm PCB clearance |
| INA, INB, INC, IND | Digital input channels | Unidirectional CMOS-compatible inputs referenced to VDD1/GND1; no external pull-ups required |
| VDD2 | Output-side power supply | Supplies isolated side (channels A–D outputs); independent 1.8–5 V rail; enables level translation |
| GND2 | Output-side ground reference | Reference for VDD2 and all output signals; galvanically isolated from GND1; defines secondary domain |
| OUTA, OUTB, OUTC, OUTD | Digital output channels | CMOS outputs referenced to VDD2/GND2; fail-safe high when VDD1 disabled or inputs inactive |
| DISABLE1 | Input-side disable control | Active-high input that forces all outputs to fail-safe state; requires pull-down current of 9–15 µA when asserted |
| VE2 | Output-enable control | Active-low enable for outputs; internal pull-up draws −3 to −10 µA when pulled low; tristates outputs when active |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Monolithic air-core transformers replace LEDs and photodiodes - eliminates LED aging, enables 125°C operation and >50-year lifetime |
| DC-correct output behavior | Maintains last valid logic state indefinitely without input toggling - essential for watchdog and status monitoring in low-activity modes |
| Independent dual-supply operation | VDD1 and VDD2 operate at different voltages (e.g., 3.3 V MCU ↔ 5 V actuator) - eliminates external level shifters in bidirectional signal paths |
| Reinforced insulation certification | UL 1577 (5 kVrms), VDE 0884-17 (849 Vpeak), IEC 60601-1 (2 MOPP) - certified for patient-connected medical devices |
| Low dynamic power consumption | 0.01 mA/Mbps input + 0.02 mA/Mbps output - reduces heat generation in dense isolation arrays for multi-axis motion controllers |

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 |
|---|---|---|---|
| ADUM241E0BRWZ-RL | Pin-compatible but with fail-safe low output state instead of high; identical SOIC_W package and 5 kVrms rating | Suitable where default-low assertion is required for safety interlocks (e.g., emergency stop logic) | Select ADUM241E0BRWZ-RL only if system-level fail-safe behavior mandates low-state default on power loss |
| SI8641ED-B-IS | Capacitive isolation; 5 kVrms; 150 Mbps; SOIC-16; VIORM = 800 Vpeak; lacks IEC 60601-1 2 MOPP certification | Valid for industrial automation but not certified for patient-connected medical devices | Choose SI8641ED-B-IS only when medical regulatory compliance is not required and capacitive isolation suffices |
Compared with ADUM241E0BRWZ-RL, the ADUM241D0BRWZ-RL provides fail-safe high output critical for active-enable gate drivers; compared with SI8641ED-B-IS, it delivers certified 2 MOPP isolation for IEC 60601-1 systems where patient safety mandates reinforced barrier validation.

FAQ
What is the maximum guaranteed data rate for ADUM241D0BRWZ-RL?
The ADUM241D0BRWZ-RL guarantees a maximum data rate of 150 Mbps across its full operating temperature range (−40°C to +125°C) and supply range (1.8 V to 5 V). This value is validated per test condition CL = 15 pF and CMOS signal levels, ensuring robust SPI and digital interface performance in real-world designs.
Does ADUM241D0BRWZ-RL support level translation between different supply voltages?
Yes, ADUM241D0BRWZ-RL supports true bidirectional level translation: VDD1 (input side) and VDD2 (output side) can operate independently at any voltage from 1.8 V to 5 V. This allows direct interfacing between 3.3 V microcontrollers and 5 V peripherals without external level-shifting components.
What safety certifications does ADUM241D0BRWZ-RL hold?
ADUM241D0BRWZ-RL is certified to UL 1577 (5 kVrms), DIN EN IEC 60747-17 (VDE 0884-17, 849 Vpeak), IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 62368-1. These approvals validate its use in medical, industrial, and consumer applications requiring reinforced insulation.
How does the fail-safe output behavior work on ADUM241D0BRWZ-RL?
When VDD1 is unpowered or DISABLE1 is asserted high, ADUM241D0BRWZ-RL forces all four outputs (OUTA–OUTD) to a logic high state. This behavior is hardwired into the silicon design and requires no external components - ensuring predictable shutdown in safety-critical gate driver or alarm circuits.
What is the creepage and clearance distance for ADUM241D0BRWZ-RL's SOIC_W package?
The ADUM241D0BRWZ-RL in RW-16 SOIC_W package provides minimum external creepage and clearance of 7.8 mm between input (Pins 1–8) and output (Pins 9–16) sides. This meets IEC 62368-1 and IEC 60601-1 requirements for reinforced insulation at pollution degree 2 and altitudes ≤2000 m.
