Analog Devices Inc. ADUM241E0BRWZ

Overview

ADUM241E0BRWZ from Analog Devices is a quad-channel digital isolator based on iCoupler® technology, providing 5.0 kV_rms reinforced insulation for high-noise industrial and medical systems. It delivers 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, and operates across 1.8 V to 5 V supply rails with level translation capability. It is used in SPI isolation for isolated ADCs and motor control gate drivers where signal integrity and safety compliance are critical.

For engineers reviewing the ADUM241E0BRWZ datasheet, ADUM241E0BRWZ pinout, ADUM241E0BRWZ application, or ADUM241E0BRWZ equivalent, key selection criteria include its 849 V_peak VIORM rating, DIN EN IEC 60747-17 (VDE 0884-17) certification, fail-safe high output option, and SOIC_W (RW-16) package with 7.8 mm creepage/clearance.

Technical Context

The ADUM241E0BRWZ implements four independent unidirectional channels with input-side power (VDD1) and output-side power (VDD2) fully decoupled, enabling galvanic isolation between domains operating at different logic voltages. Its monolithic air-core transformer architecture ensures dc-correct output states without input transitions and supports fail-safe high output behavior when input power is absent.

It features tight channel matching (≤3.0 ns codirectional skew), low jitter (70 ps rms at 5 V), and robust common-mode transient immunity of 100 kV/µs - validated under 1000 V common-mode step with 800 V transient magnitude. The device meets reinforced insulation requirements per IEC/CSA 60601-1 (2 MOPP) and IEC/CSA 61010-1 (Overvoltage Category III).

FAQ

What is the maximum guaranteed data rate for ADUM241E0BRWZ?

The ADUM241E0BRWZ 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). This value is validated per datasheet Table 1 through Table 7 under specified test conditions including CL = 15 pF and CMOS signal levels. Higher rates may be achievable but are not production-guaranteed.

Does ADUM241E0BRWZ support level translation between different supply voltages?

Yes, ADUM241E0BRWZ supports bidirectional level translation: VDD1 can operate from 1.8 V to 5 V independently of VDD2, which also ranges from 1.8 V to 5 V. This allows interfacing a 1.8 V FPGA I/O bank with a 5 V microcontroller peripheral, for example. Input thresholds scale with respective VDD, and output drive strength adapts accordingly - all confirmed in DC specifications tables for 1.8 V, 2.5 V, 3.3 V, and 5 V operation.

What safety certifications does ADUM241E0BRWZ hold?

ADUM241E0BRWZ holds UL 1577 (5000 V_rms, 1 min), DIN EN IEC 60747-17 (VDE 0884-17), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1 certifications. Its RW-16 SOIC_W package achieves 849 V_peak VIORM and 7.8 mm creepage/clearance - verified in Tables 9, 12, and 13 of the Rev. E datasheet.

How does the fail-safe high output function in ADUM241E0BRWZ work?

In ADUM241E0BRWZ, the outputs default to logic high when VDD1 is unpowered or when DISABLE1 is asserted high. This behavior is intrinsic to the E0 variant's internal design and does not require external pull-ups. It ensures defined states during power-up, brownout, or input-side fault conditions - critical for enabling gate drivers or holding system enables active until initialization completes.

Is ADUM241E0BRWZ pin compatible with earlier ADuM240x devices?

Yes, ADUM241E0BRWZ is pin compatible with ADuM2400, ADuM2401, and ADuM2402 per datasheet Feature section and Ordering Guide. This allows direct replacement in existing layouts without PCB revision, delivering improved propagation delay (13 ns vs. 25 ns), higher CMTI (100 kV/µs vs. 25 kV/µs), and updated safety certifications while retaining identical SOIC_W footprint and pin assignments.
