Product details

Overview

ADUM240E1BRIZ from Analog Devices is a quad-channel, 5.0 kV_rms reinforced digital isolator using iCoupler® technology, designed for high-noise industrial and medical interfaces. It delivers 150 Mbps data rate, 13 ns max propagation delay at 5 V, 100 kV/µs common-mode transient immunity, and operates across 1.8 V to 5 V supply rails-enabling level translation in SPI isolation and motor control gate driver feedback loops.

For engineers reviewing the ADUM240E1BRIZ datasheet, ADUM240E1BRIZ pinout, ADUM240E1BRIZ application, or ADUM240E1BRIZ equivalent, this page provides verified package mapping (16-lead SOIC_W), fail-safe output configuration (high), safety certifications (UL, VDE, IEC 62368-1, IEC 60601-1), and real-world design implications for PCB layout, voltage translation, and high-CMTI signal integrity.

Technical Context

The ADUM240E1BRIZ implements four independent unidirectional CMOS-isolated channels with monolithic air-core transformer coupling, ensuring dc-correct output states without input transitions. Its architecture supports asymmetric supply operation (e.g., 1.8 V on side 1, 3.3 V on side 2) and includes integrated undervoltage lockout (UVLO) with 1.6 V threshold and 0.1 V hysteresis per side.

It features a fail-safe high output state when inputs are disabled or power is lost, and supports tristate outputs via dedicated ENABLE/ DISABLE pins. Channel matching is ≤3.0 ns (codirectional), and pulse width distortion remains ≤3 ns across temperature and voltage ranges-critical for timing-sensitive serial protocols like isolated SPI and RS-485 transceiver control.

Pinout & Package

ADUM240E1BRIZ uses a 16-lead, RoHS-compliant wide-body SOIC package (RW-16 / SOIC_W), with 7.8 mm creepage and clearance, rated for 5.0 kV_rms reinforced insulation. Input-side pins (1–8) and output-side pins (9–16) are physically segregated to maintain isolation integrity.

Pin/Terminal	Circuit Role	Design Meaning

5, 6, 7, 8 (GND1)	Input-side ground reference	Return path for VDD1; must be separated from GND2 by ≥7.8 mm on PCB.
9, 10, 11, 12 (VDD2)	Output-side power supply	Independent 1.8 V–5 V rail; enables bidirectional level translation across isolation barrier.
13, 14, 15, 16 (GND2)	Output-side ground reference	Return path for VDD2; galvanically isolated from GND1; defines secondary-side noise floor.
A1, B1, C1, D1 (Pins 1–4)	Input data channels	CMOS-compatible inputs; VIH = 0.7×VDD1, VIL = 0.3×VDD1; support 150 Mbps toggle rates.
A2, B2, C2, D2 (Pins 9–12)	Output data channels	CMOS outputs with VOH ≥ VDD2 − 0.4 V @ 4 mA; VOL ≤ 0.4 V @ 4 mA; fail-safe high when disabled.

Key Features

Feature	Design Value

1.8 V to 5 V dual-supply operation	Enables direct connection between ultra-low-power MCUs (1.8 V) and legacy 3.3 V/5 V peripherals-no external level shifters required.
Fail-safe high output	Guarantees logic-high outputs during power loss or input disable-critical for enabling gate drivers or disabling safety relays.
UL, VDE, and IEC 60601-1 certification	Validated reinforced insulation (849 V_peak) supports Class I/II medical devices and industrial equipment requiring 2 MOPP.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM2400ARWZ	Same 5.0 kV_rms SOIC_W package but with fail-safe low output and no ENABLE pin; 100 Mbps max data rate.	Limited to applications where active-low enable or lower speed suffices (e.g., legacy industrial sensors).	Select ADUM2400ARWZ only if fail-safe low behavior matches system reset logic and 100 Mbps bandwidth is sufficient.
SI8641ED-B-IS	4-channel, 5.0 kV_rms capacitive isolator; 150 Mbps data rate; 12 ns max propagation delay; different pinout (SOIC-16, non-pin-compatible).	Requires PCB redesign due to differing pin assignment and lack of native 1.8 V–5 V level translation support.	Choose SI8641ED-B-IS only when migrating to Silabs ecosystem or needing tighter propagation delay spec, accepting layout change.

Compared with ADUM2400ARWZ and SI8641ED-B-IS, the ADUM240E1BRIZ uniquely combines fail-safe high output, 150 Mbps performance, and full 1.8 V–5 V dual-supply flexibility in a pinout-compatible upgrade path from ADUM2400-making it optimal for new designs requiring robustness, speed, and voltage interoperability without board rework.

FAQ

What is the maximum guaranteed data rate for ADUM240E1BRIZ?

The ADUM240E1BRIZ guarantees a maximum data rate of 150 Mbps across all operating conditions (−40°C to +125°C, 1.8 V–5 V supplies). This is validated with CL = 15 pF loads and CMOS-level signals. While higher rates may function, 150 Mbps is the only value specified with full timing margin and jitter compliance (≤70 ps rms).

Does ADUM240E1BRIZ support level translation between different supply voltages?

Yes, ADUM240E1BRIZ supports true bidirectional level translation: VDD1 can operate from 1.8 V to 5 V independently of VDD2 (also 1.8 V–5 V). For example, it can translate 1.8 V logic from an MCU to 3.3 V logic on an ADC side, with input thresholds scaling to 0.7×VDD1 and outputs referenced to VDD2-no external components needed.

What safety certifications does ADUM240E1BRIZ hold?

ADUM240E1BRIZ is certified to UL 1577 (5000 V_rms, 1 min), DIN EN IEC 60747-17 (VDE 0884-17, 849 V_peak reinforced), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1. These approvals are specific to the RW-16 SOIC_W package and validate its use in medical, industrial, and test equipment.

How does the fail-safe high feature work on ADUM240E1BRIZ?

When the input-side power (VDD1) is absent or the DISABLE1 pin is asserted, the ADUM240E1BRIZ forces all four outputs (A2–D2) to logic high. This behavior is hardware-defined and requires no external pull-ups. It ensures predictable deactivation of downstream circuits-such as disabling IGBT gate drivers during power loss.

Is ADUM240E1BRIZ pin-compatible with earlier ADUM2400 series devices?

Yes, ADUM240E1BRIZ is pin-compatible with ADUM2400/ADUM2401/ADUM2402 in the same RW-16 SOIC_W package. It retains identical pin functions and footprint but upgrades to 150 Mbps data rate, improved CMTI (100 kV/µs), and fail-safe high output-enabling drop-in replacement in existing designs with enhanced performance.
