Product details

Overview

ADUM141E1WBRWZ-RL from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation technology, providing 3.0 kV_RMS withstand voltage in a 16-lead SOIC_W (wide-body) package. It supports 150 Mbps data rate, 15 ns max propagation delay at 1.8 V, and operates across 1.8 V to 5 V supply rails with level translation capability. It is used in SPI/data converter isolation for industrial PLCs and motor drives where high noise immunity and fail-safe operation are required.

For engineers reviewing the ADUM141E1WBRWZ-RL datasheet, ADUM141E1WBRWZ-RL pinout, ADUM141E1WBRWZ-RL application, or ADUM141E1WBRWZ-RL equivalent, key selection criteria include common-mode transient immunity (100 kV/µs), AEC-Q100 qualification, VDE 0884-17 reinforced insulation, and pin compatibility with legacy ADuM1400-series devices.

Technical Context

The ADUM141E1WBRWZ-RL implements four independent unidirectional CMOS-isolated channels using monolithic air-core transformers, enabling dc-correct output states without input transitions. Its architecture ensures tight channel matching (≤3.0 ns codirectional skew) and low jitter (70 ps rms at 5 V).

It features dual supply domains (VDD1/VDD2), undervoltage lockout (1.5 V–1.6 V thresholds), and configurable fail-safe outputs (high or low on power loss). The device meets IEC/EN/CSA 60950-1, 60601-1, and 61010-1 safety standards with VIORM = 565 V_peak and DIN EN IEC 60747-17 (VDE 0884-17) certification.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM140E1WBRWZ-RL	Same SOIC_W package and 3.0 kV_RMS rating, but lower 100 Mbps data rate and 20 ns max propagation delay at 1.8 V.	Targeted at cost-sensitive industrial I/O modules where 150 Mbps is unnecessary.	Select when system timing budget allows ≥20 ns delay and data rate ≤100 Mbps.
SI8641ED-B-IS	Capacitive isolation; 5000 V_RMS rating; 150 Mbps; 13 ns max delay at 5 V; different pinout (16-pin SOIC_N).	Requires PCB redesign due to narrower SOIC_N footprint and non-pin-compatible layout.	Choose for higher isolation voltage needs where board space permits SOIC_N and layout revision is feasible.

Compared with ADUM141E1WBRWZ-RL, ADUM140E1WBRWZ-RL trades speed for cost in fixed-rate systems, while SI8641ED-B-IS offers higher voltage rating at the expense of pin compatibility and capacitive-noise coupling behavior.

FAQ

What is the maximum guaranteed data rate for ADUM141E1WBRWZ-RL?

The ADUM141E1WBRWZ-RL guarantees a maximum data rate of 150 Mbps across its full operating temperature range (−40°C to +125°C) and supply voltage range (1.8 V to 5 V), as verified in the Rev. K datasheet Table 1 through Table 7 under switching specifications.

Does ADUM141E1WBRWZ-RL support level translation between different supply voltages?

Yes, ADUM141E1WBRWZ-RL supports true bidirectional level translation: VDD1 can operate from 1.8 V to 5 V independently of VDD2, enabling direct interface between 1.8 V microcontrollers and 3.3 V or 5 V peripherals without external level-shifting circuitry.

Is ADUM141E1WBRWZ-RL certified for medical applications?

Yes, ADUM141E1WBRWZ-RL is certified to IEC/CSA 60601-1 and DIN EN IEC 60747-17 (VDE 0884-17), making it suitable for patient-connected medical equipment requiring reinforced insulation and low leakage current compliance.

What is the fail-safe behavior of ADUM141E1WBRWZ-RL on primary-side power loss?

When VDD1 is removed or falls below UVLO threshold (1.5 V), the ADUM141E1WBRWZ-RL outputs transition to a predefined high state - a critical feature for maintaining safe default logic levels in motor control and BMS applications.

How does ADUM141E1WBRWZ-RL compare to optocouplers in terms of lifetime reliability?

Unlike optocouplers subject to LED degradation and current transfer ratio (CTR) drift, ADUM141E1WBRWZ-RL uses solid-state iCoupler® transformers with no wear-out mechanism, delivering >50 years of operational life at 125°C per Analog Devices' reliability modeling.
