Analog Devices Inc. ADUM341E0WBRWZ

Overview

ADUM341E0WBRWZ from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation, providing 5.7 kV_rms reinforced isolation in a 16-lead SOIC (RW-16) package. It features fail-safe low (E0) output logic, 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 on both sides - enabling level translation and robust SPI or CAN FD bus isolation in industrial motor drives.

For engineers reviewing the ADUM341E0WBRWZ datasheet, ADUM341E0WBRWZ pinout, ADUM341E0WBRWZ application, or ADUM341E0WBRWZ equivalent, key selection criteria include its 180 kV/µs common-mode transient immunity, AEC-Q100 qualification for automotive use, VDE-certified 1173 V_peak working voltage, and guaranteed 10 ns max propagation delay under full temperature range (−40°C to +125°C).

Technical Context

The ADUM341E0WBRWZ implements four independent unidirectional CMOS-isolated channels using monolithic air-core transformers, with integrated driver/receiver circuitry on each side. Its architecture supports asymmetric supply operation (e.g., 3.3 V primary / 5 V secondary), and includes undervoltage lockout (UVLO) with 2.2 V enable threshold and 0.2 V hysteresis on both VDD1 and VDD2 rails.

It delivers tight channel matching (≤3.0 ns codirectional skew), low jitter (7.19 ps RMS random jitter at 1 MHz), and failsafe E0 logic - where outputs default to low when input-side power is absent. The device meets DIN EN IEC 60747-17 (VDE 0884-17) and UL 1577 standards, with VIORM = 1173 V_peak and VISO = 5700 V_rms for 1 minute in SOIC RW-16 packaging.

Key Specifications

Pinout & Package

FAQ

What is the maximum guaranteed data rate for ADUM341E0WBRWZ at 3.3 V operation?

The ADUM341E0WBRWZ guarantees up to 150 Mbps data rate at 3.3 V operation, as confirmed in Table 3 of the Rev. C datasheet under "Data Rate" with "Within PWD limit" condition. This performance holds across the full temperature range (−40°C to +125°C) and is validated with CL = 15 pF loading and CMOS signal levels. The device maintains this rate while delivering <3 ns pulse width distortion and 6.6 ns typical propagation delay at 3.3 V.

Does ADUM341E0WBRWZ support independent supply voltages on each side?

Yes, ADUM341E0WBRWZ supports fully independent supply rails: VDD1 (2.25 V to 5.5 V) powers the input side, and VDD2 (2.25 V to 5.5 V) powers the output side. This enables level translation - for example, interfacing a 3.3 V microcontroller (VDD1) with a 5 V FPGA (VDD2) - without external level shifters. The datasheet specifies operation across all combinations within the rated ranges, including 2.5 V/5.5 V and 3.3 V/2.5 V configurations.

What safety certifications apply to ADUM341E0WBRWZ in the SOIC RW-16 package?

ADUM341E0WBRWZ in the SOIC RW-16 package is certified to DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 1173 V_peak, UL 1577 with VISO = 5700 V_rms for 1 minute, IEC/EN/CSA 62368-1, IEC/CSA 60601-1, IEC/CSA 61010-1, and CQC GB4943.1. These approvals validate its use as reinforced insulation in medical, industrial, and consumer safety-critical applications per applicable regional standards.

How does the E0 fail-safe logic behave during input-side power loss?

When VDD1 is removed or falls below UVLO threshold (≤1.8 V), the ADUM341E0WBRWZ E0 variant forces all four outputs (OUTA–OUTD) to logic low, regardless of EN2 state. This behavior is inherent to the E0 configuration and provides predictable safe-state signaling for downstream gate drivers or fault monitors. The transition occurs within the UVLO release time of 60 µs after VDD1 crosses the falling threshold.

Is ADUM341E0WBRWZ pin-compatible with earlier ADuM14xx or ADuM24xx isolators?

No, ADUM341E0WBRWZ is not pin-compatible with ADuM14xx or ADuM24xx families due to differences in enable pin assignment (EN1/EN2), power sequencing requirements, and internal architecture. While it offers backward functional compatibility - meaning it can replace those devices in system-level design with updated layout - the pinout differs: ADUM341E0WBRWZ places EN1 on Pin 1 and EN2 on Pin 16, whereas ADuM140x uses different enable locations and lacks secondary-side enable entirely.
