Product details

Overview

ADUM141E0BRWZ from Analog Devices is a quad-channel digital isolator based on iCoupler® transformer technology, providing 3.75 kV_RMS reinforced isolation in a wide-body SOIC-16 package. It supports 150 Mbps data rate, 15 ns max propagation delay at 1.8 V operation, and 1.8 V to 5 V level translation across the isolation barrier. It is used in SPI/data converter isolation for industrial PLCs and motor drives where high noise immunity and fail-safe output states are required.

For engineers reviewing the ADUM141E0BRWZ datasheet, ADUM141E0BRWZ pinout, ADUM141E0BRWZ application, or ADUM141E0BRWZ equivalent, key selection criteria include its 3.75 kV_RMS isolation rating, 100 kV/µs common-mode transient immunity, AEC-Q100 qualification, and E0 fail-safe configuration (outputs default high when input side is unpowered).

Technical Context

The ADUM141E0BRWZ implements four independent unidirectional CMOS-isolated channels using monolithic air-core transformers, ensuring dc-correct output behavior without input transitions. Its architecture supports asymmetric supply operation (e.g., 1.8 V on side 1, 5 V on side 2), enabling voltage-level translation while maintaining timing integrity.

It features two enable inputs (VE1, VE2) controlling output tristate states per side, and includes undervoltage lockout (UVLO) with 1.6 V threshold on both VDD1 and VDD2. The device meets DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation and carries UL, CSA, and CQC safety certifications.

VDD1	Input-side power supply	Supplies 1.8–5 V to input-side logic and channel transmitters; UVLO active below 1.5 V
GND1	Input-side ground reference	Return path for VDD1; must be isolated from GND2 by ≥7.8 mm PCB spacing
VA, VB, VC, VD	Input signal terminals	Accept CMOS-level signals; VIH = 0.7×VDD1, VIL = 0.3×VDD1
VE1	Input-side output enable	Active-low; pulls all side-1 outputs to high-impedance when asserted
VDD2	Output-side power supply	Supplies 1.8–5 V to output-side logic and receivers; independent of VDD1
GND2	Output-side ground reference	Return path for VDD2; galvanically separated from GND1
OA, OB, OC, OD	Isolated output terminals	CMOS-compatible outputs; VOH ≥ VDD2 − 0.4 V @ 4 mA, VOL ≤ 0.4 V @ 4 mA
VE2	Output-side output enable	Active-low; places all side-2 outputs in high-impedance state when asserted

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad digital isolator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM141D0BRWZ	Same RW-16 package and 3.75 kV_RMS rating, but D0 fail-safe (outputs default low when VDD1 is absent)	Preferred in systems where inactive-state logic low is required for safety interlocks (e.g., emergency stop circuits)	Select ADUM141D0BRWZ only if hardware design requires low-default outputs; otherwise ADUM141E0BRWZ is optimal for high-default safety logic.
SI8641ED-B-IS	Capacitive isolation; 3.75 kV_RMS; 150 Mbps; but no AEC-Q100 qualification and lower CMTI (75 kV/µs)	Suitable for industrial automation but not automotive or medical applications requiring certified reliability	Choose SI8641ED-B-IS only for cost-sensitive non-automotive designs where AEC-Q100 and 100 kV/µs CMTI are not mandatory.

Compared with ADUM141D0BRWZ and SI8641ED-B-IS, ADUM141E0BRWZ uniquely combines AEC-Q100 qualification, 100 kV/µs CMTI, and E0 fail-safe behavior-making it the only option qualified for automotive BMS and medical 2×MOPP systems requiring high-default safety states.

FAQ

What is the isolation voltage rating of the ADUM141E0BRWZ?

The ADUM141E0BRWZ has a rated dielectric insulation voltage of 3.75 kV_RMS for 1 minute, verified per UL 1577 and DIN EN IEC 60747-17. This rating applies to the RW-16 wide-body SOIC package and supports reinforced insulation in medical (IEC 60601-1) and industrial (IEC 62368-1) equipment.

Does the ADUM141E0BRWZ support level translation between different supply voltages?

Yes, the ADUM141E0BRWZ supports independent 1.8 V to 5 V supplies on each side, enabling bidirectional level translation across the isolation barrier. For example, it can interface a 1.8 V FPGA I/O bank with a 5 V microcontroller SPI peripheral without external level shifters.

What does the "E0" suffix indicate in ADUM141E0BRWZ?

The "E0" suffix denotes the fail-safe output configuration: when the input-side supply (VDD1) is unpowered or disabled, all output-side pins (OA–OD) default to logic high. This behavior is confirmed in the datasheet's Ordering Guide and Truth Tables sections for ADUM141E0 models.

Is the ADUM141E0BRWZ qualified for automotive applications?

Yes, the ADUM141E0BRWZ is AEC-Q100 qualified for Grade 1 (−40°C to +125°C), making it suitable for automotive battery management systems, onboard chargers, and ADAS sensor interfaces where long-term reliability under thermal stress is mandatory.

How does the ADUM141E0BRWZ compare to optocouplers in terms of timing performance?

The ADUM141E0BRWZ achieves 15 ns maximum propagation delay and <3 ns pulse width distortion at 1.8 V, far exceeding typical optocouplers (often >100 ns delay, >20 ns skew). Its channel matching of ≤3.0 ns ensures deterministic timing across all four channels-critical for synchronized sampling and PWM control.
