Product details

Overview

ADUM241D1BRWZ from Analog Devices is a quad-channel, 5.0 kV_rms digital isolator using iCoupler® transformer-based technology. It provides bidirectional signal isolation with 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, and fail-safe high output configuration. It is used in SPI isolation for industrial PLCs where galvanic separation between microcontroller and ADC/DAC interfaces is required.

For engineers reviewing the ADUM241D1BRWZ datasheet, ADUM241D1BRWZ pinout, ADUM241D1BRWZ application, or ADUM241D1BRWZ equivalent, key selection criteria include reinforced insulation rating (849 V_peak), 1.8 V to 5 V dual-supply level translation, high common-mode transient immunity (100 kV/µs), and SOIC_W-16 package compatibility with IPC-7351B land patterns.

Technical Context

The ADUM241D1BRWZ implements four independent unidirectional channels with input-side power (VDD1) and output-side power (VDD2) operating independently across 1.8 V–5 V. Its iCoupler® architecture replaces optocouplers with monolithic air-core transformers, ensuring dc-correct output states without input transitions.

It features two enable inputs (VE1, VE2) controlling channel groups, undervoltage lockout (1.6 V threshold), and fail-safe high output behavior when input power is absent. Channel matching is ≤3.0 ns, and pulse width distortion remains ≤3 ns across temperature and voltage ranges.

Key Specifications

Parameter	Value and Actual Design Meaning
Isolation Rating	5.0 kV_rms for 1 minute - meets reinforced insulation requirements per IEC/EN 60747-17 (VDE 0884-17) and UL 1577.
Data Rate	150 Mbps guaranteed - supports high-speed SPI, RS-485, and digital fieldbus protocols without timing margin loss.
Propagation Delay	≤13 ns at 5 V - enables tight-tolerance timing in real-time control loops and synchronized sampling systems.
Common-Mode Transient Immunity	100 kV/µs - maintains signal integrity in noisy motor drive or power converter environments with fast switching transients.
Supply Voltage Range	1.8 V to 5 V on both sides - allows direct interfacing between low-voltage MCUs (1.8 V/3.3 V) and higher-voltage peripherals (5 V).
Fail-Safe Output State	High - ensures defined logic-high default on output side during power loss or disable, critical for safety-critical enable/disable paths.
Operating Temperature	−40°C to +125°C - qualified for under-hood automotive and industrial ambient conditions without derating.

Pinout & Package

ADUM241D1BRWZ uses a 16-lead, RoHS-compliant, wide-body SOIC_W (RW-16) 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 supply	Power for channels A/B; accepts 1.8 V–5 V; UVLO active below 1.5 V.
GND1	Input-side ground	Reference for input logic and internal circuitry; must be isolated from GND2.
VA, VB	Input data channels	CMOS-compatible inputs referenced to VDD1; support 150 Mbps operation.
VE1	Enable input (Group 1)	Active-high enable for channels A/B; pulls up internally when not driven.
VDD2	Output-side supply	Power for channels C/D; independent 1.8 V–5 V domain; enables level translation.
GND2	Output-side ground	Reference for output logic; galvanically isolated from GND1.
VC, VD	Output data channels	CMOS outputs referenced to VDD2; fail-safe high when disabled or unpowered.
VE2	Enable input (Group 2)	Active-high enable for channels C/D; internal pull-up ensures enabled state if left floating.

Key Features

Feature	Design Value
iCoupler® transformer isolation	Eliminates LED aging and CTR degradation of optocouplers; guarantees >50-year insulation lifetime per IEC 60747-17.
Dual-supply level translation	Enables seamless interface between 1.8 V MCU GPIO and 5 V sensor bus without external level shifters.
Fail-safe high output	Prevents undefined states in safety-critical paths (e.g., motor gate driver enable) during power fault or reset.
100 kV/µs CMTI	Rejects fast dv/dt noise from SiC/GaN inverters, avoiding false triggering in isolated gate drivers or current sensing.
Automotive qualification	AEC-Q100 Grade 1 (−40°C to +125°C) compliance supports use in EV battery management and ADAS subsystems.

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; 5.0 kV_rms; 150 Mbps; 13 ns max delay; 16-pin SOIC_W; failsafe high.	Same reinforced insulation rating and pinout, but different CMTI (85 kV/µs) and lower temp range (−40°C to +105°C).	Preferred where lower cost and established capacitive-isolator supply chain are prioritized over extended temperature support.
ISO6741FDWR	Capacitive isolation; 5.0 kV_rms; 50 Mbps; 25 ns max delay; 16-pin SOIC_W; failsafe high.	Lower data rate and slower propagation limit suitability to non-high-speed SPI or slower UART isolation.	Select when system timing budget allows ≥25 ns delay and 50 Mbps is sufficient, favoring TI's long-term availability program.

Compared with SI8641ED-B-IS and ISO6741FDWR, ADUM241D1BRWZ delivers superior high-temperature operation (125°C vs. 105°C/105°C), higher CMTI (100 kV/µs vs. 85/75 kV/µs), and tighter channel matching (3.0 ns vs. 5.0/7.0 ns), making it optimal for demanding industrial and automotive timing-critical designs.

FAQ

What is the maximum guaranteed data rate for ADUM241D1BRWZ?

The ADUM241D1BRWZ has a maximum guaranteed data rate of 150 Mbps across all operating voltages (1.8 V to 5 V) and temperatures (−40°C to +125°C), verified per the datasheet's switching specifications tables and tested with 15 pF load and CMOS signal levels.

Does ADUM241D1BRWZ support level translation between different supply voltages?

Yes, ADUM241D1BRWZ supports true bidirectional level translation: VDD1 (input side) and VDD2 (output side) operate independently from 1.8 V to 5 V, enabling direct interface between 1.8 V microcontrollers and 5 V peripherals without external level-shifting circuitry.

What safety certifications does ADUM241D1BRWZ hold?

ADUM241D1BRWZ is certified to UL 1577 (5000 V_rms, 1 min), DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation (849 V_peak), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1, as documented in Tables 12 and 13 of the Rev. E datasheet.

How does the fail-safe high output behavior work on ADUM241D1BRWZ?

When VDD1 is unpowered or the enable inputs (VE1/VE2) are deasserted, the ADUM241D1BRWZ output channels (VC/VD) default to logic high. This behavior is implemented via internal circuitry and ensures safe shutdown states in motor control or power supply enable paths.

What is the package type and creepage distance of ADUM241D1BRWZ?

ADUM241D1BRWZ uses the RW-16 wide-body SOIC_W package with minimum external creepage and clearance of 7.8 mm, compliant with IEC 62368-1 and IEC 60601-1 for pollution degree 2 and altitudes ≤2000 m.
