Product details
Overview
ADUM341E1BRWZ from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation, providing 5.7 kVrms reinforced insulation in a 16-lead SOIC (RW-16) package. It delivers 150 Mbps data rate at 5 V, 6.2 ns typical propagation delay, and operates across 2.25 V to 5.5 V supply rails with fail-safe high (E1) output logic state on power loss.
For engineers reviewing the ADUM341E1BRWZ datasheet, ADUM341E1BRWZ pinout, ADUM341E1BRWZ application, or ADUM341E1BRWZ equivalent, this device is selected for high-speed industrial bus isolation (e.g., CAN FD, RS-485), SPI data converter interfaces, and PWM signal conditioning where robust noise immunity (>100 kV/µs CMTI), low jitter (<292 ps TJ), and AEC-Q100 qualification are required.
Technical Context
The ADUM341E1BRWZ integrates four independent unidirectional isolation channels using monolithic air-core transformers, enabling precise timing control with ≤3.0 ns channel matching and <3 ns pulse width distortion at 5 V. Its dual-supply architecture supports level translation between 2.25 V and 5.5 V domains without external components.
It implements fail-safe logic via dedicated enable inputs (VE1/VE2), ensuring outputs default to high when input-side power is absent. Safety compliance includes VISO = 5700 Vrms for 1 minute and VIORM = 1173 Vpeak, certified to DIN EN IEC 60747-17 (VDE 0884-17), UL 1577, and IEC/EN/CSA 62368-1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 150 Mbps maximum - supports high-speed serial protocols like CAN FD and SPI without timing bottlenecks. |
| Propagation Delay | 6.2 ns typical (10 ns max) at 5 V - enables tight timing budgets in real-time control loops. |
| Common-Mode Transient Immunity | 180 kV/µs typical - maintains signal integrity in noisy motor drives and industrial inverters. |
| Supply Voltage Range | 2.25 V to 5.5 V per side - allows direct interfacing with mixed-voltage systems (e.g., 3.3 V MCU to 5 V sensor). |
| Isolation Rating | 5700 Vrms for 1 minute (SOIC RW-16) - meets reinforced insulation requirements for functional safety in industrial equipment. |
| Fail-Safe Output | High (E1) - guarantees known logic state during input-side power failure, critical for safe shutdown sequencing. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and high-temperature industrial environments. |
| ESD Protection | ±8 kV IEC 61000-4-2 across barrier - reduces need for external transient suppression in field-deployed systems. |
Pinout & Package
ADUM341E1BRWZ uses a 16-lead wide-body SOIC package (RW-16), 10.3 mm × 7.5 mm, RoHS-compliant, with creepage/clearance ≥8.3 mm. Pinout follows standard ADuM34xE channel assignment with independent input/output pairs and dual enable controls.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Input-side power supply | Supplies logic and isolation transmitter circuitry; accepts 2.25–5.5 V. |
| GND1 | Input-side ground reference | Return path for VDD1; must be isolated from GND2 by ≥8.3 mm creepage. |
| VA, VB, VC, VD | Input data channels A–D | CMOS-compatible inputs accepting 0.3×VDD1 to 0.7×VDD1 thresholds. |
| VE1 | Input-side enable (active low) | Pulls outputs high when asserted; internal pull-up ensures fail-safe E1 behavior on power loss. |
| VDD2 | Output-side power supply | Supplies isolation receiver and output drivers; independent voltage domain from VDD1. |
| GND2 | Output-side ground reference | Return path for VDD2; galvanically isolated from GND1. |
| OA, OB, OC, OD | Output data channels A–D | CMOS outputs driving loads up to 4 mA; VOH = VDD2 − 0.1 V, VOL = 0.1 V max. |
| VE2 | Output-side enable (active low) | Controls tristate mode of OA–OD; high-Z state entered within 12 ns of assertion. |
Key Features
| Feature | Design Value |
|---|---|
| Quad unidirectional isolation channels | Four independent signal paths with no cross-talk coupling; supports asymmetric data flow (e.g., SPI master-to-slave + slave-to-master). |
| iCoupler® transformer technology | Monolithic air-core transformers eliminate optocoupler aging and enable >100-year insulation lifetime per IEC 60664-1. |
| Low-power operation | <1.65 mA/channel at 1 Mbps - reduces thermal load in dense PCB layouts and extends battery life in portable test equipment. |
| Backward compatibility | Pin- and function-compatible with ADuM140E/ADuM240E families - enables drop-in upgrade without layout changes. |
| AEC-Q100 Grade 1 qualification | Validated for automotive applications including body electronics and battery management systems requiring −40°C to +125°C operation. |
| Integrated UVLO protection | 2.2 V rising threshold with 0.2 V hysteresis prevents erratic switching during brown-out conditions on either side. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM340E1BRWZ | Same 16-pin SOIC RW-16 package and 5.7 kVrms rating, but with two input and two output channels (2/2 configuration vs. ADUM341E1BRWZ's 4/0). | Used where bidirectional isolation is needed on two channels instead of four unidirectional paths. | Select ADUM340E1BRWZ when isolating differential buses like I²C or bidirectional UART, not for four independent unidirectional signals. |
| SI8641ED-IS | Capacitive isolation, 5 kVrms, 150 Mbps, but only 100 kV/µs CMTI and no AEC-Q100 qualification. | Targeted at cost-sensitive industrial controls where automotive qualification is unnecessary. | Choose SI8641ED-IS for non-automotive applications where lower CMTI and absence of AEC-Q100 are acceptable trade-offs for price reduction. |
Compared with ADUM341E1BRWZ, ADUM340E1BRWZ provides bidirectional channel flexibility at identical isolation strength, while SI8641ED-IS offers lower cost but reduced noise immunity and no automotive qualification-making ADUM341E1BRWZ optimal for high-reliability, high-noise, or automotive-critical designs.

FAQ
What is the maximum data rate supported by ADUM341E1BRWZ?
ADUM341E1BRWZ supports a guaranteed maximum data rate of 150 Mbps at 5 V operation, validated across temperature (−40°C to +125°C) and supply voltage (4.5 V to 5.5 V). This performance holds within pulse width distortion limits and applies to all four channels simultaneously, making it suitable for high-speed industrial field buses such as CAN FD and RS-485.
Does ADUM341E1BRWZ support level translation between different supply voltages?
Yes, ADUM341E1BRWZ supports true bidirectional level translation: VDD1 and VDD2 can each operate independently from 2.25 V to 5.5 V. For example, it can interface a 3.3 V microcontroller (VDD1) with a 5 V sensor interface (VDD2), with input thresholds scaling to 0.3×VDDx and 0.7×VDDx, and outputs compliant to the respective VDDx rail.
What fail-safe behavior does ADUM341E1BRWZ exhibit during input-side power loss?
ADUM341E1BRWZ is an E1 variant, meaning its outputs transition to a logic high state when the input-side power (VDD1) is removed or falls below UVLO threshold (2.2 V). This behavior is enforced by internal pull-up circuitry on VE1, ensuring predictable system-level shutdown in safety-critical applications like motor control or battery management.
Is ADUM341E1BRWZ qualified for automotive applications?
Yes, ADUM341E1BRWZ is AEC-Q100 qualified for Grade 1 (−40°C to +125°C), with full documentation of stress testing, reliability validation, and failure analysis per the AEC specification. It is approved for use in automotive subsystems including battery management systems, onboard chargers, and body control modules requiring reinforced isolation.
How does the common-mode transient immunity (CMTI) of ADUM341E1BRWZ compare to legacy optocouplers?
ADUM341E1BRWZ delivers 180 kV/µs typical CMTI-over 10× higher than typical optocouplers (10–20 kV/µs). This is achieved through iCoupler® transformer coupling and proprietary noise rejection circuitry, enabling reliable operation in high-dv/dt environments such as SiC inverter gates and industrial motor drives without added filtering.
