Analog Devices Inc. ADUM240E0BRIZ

Overview

ADUM240E0BRIZ from Analog Devices is a quad-channel, 5.0 kV_rms digital isolator using iCoupler® transformer-based technology. It provides galvanic isolation between microcontroller and peripheral interfaces with 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, and fail-safe high output configuration. It is used in industrial SPI bus isolation where high noise immunity and reinforced insulation are required.

For engineers reviewing the ADUM240E0BRIZ datasheet, ADUM240E0BRIZ pinout, ADUM240E0BRIZ application, or ADUM240E0BRIZ equivalent, key selection criteria include its 5.0 kV_rms withstand voltage, 100 kV/µs common-mode transient immunity, 1.8 V to 5 V dual-supply level translation capability, and SOIC_W (RW-16) package with 7.8 mm creepage/clearance for IEC 62368-1 and IEC 60601-1 compliance.

Technical Context

The ADUM240E0BRIZ implements four independent unidirectional isolation channels using monolithic air-core transformers and integrated CMOS interface circuitry. Its input-side logic operates at 1.8 V–5 V, and output-side logic operates independently at the same voltage range, enabling bidirectional level shifting across the isolation barrier without external components.

It features dc-correct operation-maintaining output state during input inactivity-and a fail-safe high output mode activated when input power is absent or inputs are disabled. Safety certification includes UL 1577 (5000 V_rms/1 min), DIN EN IEC 60747-17 (VDE 0884-17), and IEC 60601-1 (2 MOPP).

FAQ

What is the isolation voltage rating of ADUM240E0BRIZ?

ADUM240E0BRIZ has a rated dielectric insulation voltage of 5000 V_rms for 1 minute, certified per UL 1577, DIN EN IEC 60747-17 (VDE 0884-17), and IEC 60601-1. Its reinforced insulation supports 849 V_peak working voltage (VIORM) and meets 2 MOPP requirements for patient-connected medical devices.

Does ADUM240E0BRIZ support 1.8 V logic levels on both sides?

Yes, ADUM240E0BRIZ supports independent 1.8 V to 5 V supplies on both VDD1 and VDD2, enabling true bidirectional level translation. At 1.8 V operation, it guarantees 150 Mbps data rate and 15 ns maximum propagation delay, with full functionality across −40°C to +125°C.

What is the fail-safe behavior of ADUM240E0BRIZ?

ADUM240E0BRIZ is an "E0" variant with fail-safe high output: when VDD1 is unpowered or inputs are disabled (via DISABLE1), all outputs (OUTA–OUTD) transition to and hold a logic high state. This prevents undefined control signals in safety-critical enable paths.

Is ADUM240E0BRIZ pin-compatible with earlier ADuM2400-series isolators?

Yes, ADUM240E0BRIZ is pin-compatible with ADuM2400ARWZ and ADuM2400CRWZ per the datasheet's backward compatibility statement. It uses the same RW-16 (SOIC_W) footprint, identical pinout, and shares identical timing and drive specifications-enabling drop-in replacement in existing designs.

What safety certifications does ADUM240E0BRIZ hold?

ADUM240E0BRIZ is certified to UL 1577 (5000 V_rms), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), IEC/CSA 61010-1, CQC GB4943.1, and DIN EN IEC 60747-17 (VDE 0884-17). The "*" marking on the device denotes VDE 0884-17 compliance with partial discharge testing.
