Analog Devices Inc. ADUM230E0BRIZ

Overview

ADUM230E0BRIZ from Analog Devices is a triple-channel, 5.0 kV_RMS digital isolator based on iCoupler® technology, designed for high-noise industrial and medical systems requiring galvanic isolation between microcontroller SPI interfaces and isolated peripherals. It delivers 150 Mbps data rate, 13 ns max propagation delay at 5 V, and operates across 1.8 V to 5 V supply rails with fail-safe high output configuration.

For engineers reviewing the ADUM230E0BRIZ datasheet, ADUM230E0BRIZ pinout, ADUM230E0BRIZ application, or ADUM230E0BRIZ equivalent, this page provides verified specifications, SOIC-16 package layout, safety-certified insulation parameters, and real-world use cases in SPI isolation, motor control feedback, and IEC 60601-1 compliant medical data acquisition.

Technical Context

The ADUM230E0BRIZ implements three independent unidirectional CMOS-isolated channels using monolithic air-core transformers, enabling dc-correct operation without input transitions-unlike optocouplers. Its architecture supports tight channel matching (≤3.0 ns) and low pulse width distortion (≤3 ns), critical for synchronized timing in isolated ADC/DAC interfaces.

It features dual-supply operation (VDD1/VDD2 = 1.7–5.5 V), 100 kV/µs common-mode transient immunity, and reinforced insulation rated to 849 V_PEAK per DIN EN IEC 60747-17 (VDE 0884-17), meeting IEC 60601-1 (2 MOPP) and IEC 62368-1 requirements for medical and industrial end equipment.

FAQ

What is the fail-safe output behavior of ADUM230E0BRIZ?

The ADUM230E0BRIZ features a fail-safe high output configuration: when VDD1 is unpowered or the DISABLE1 input is asserted, all three output channels (A, B, C) drive logic high. This behavior is confirmed in the Truth Tables section of the Rev. C datasheet and ensures predictable state during power-up, brownout, or fault conditions-critical for safety interlocks in ADUM230E0BRIZ-based designs.

Does ADUM230E0BRIZ support 1.8 V operation on both sides simultaneously?

Yes, ADUM230E0BRIZ is fully specified for 1.8 V operation on both VDD1 and VDD2 rails, with maximum propagation delay of 15 ns and 150 Mbps data rate guaranteed. Electrical Characteristics tables for 1.8 V operation (Table 7) confirm VIH/VIL thresholds at 0.7× and 0.3× VDDx, and VOH/VOL levels remain valid-enabling direct interface with ultra-low-voltage FPGAs and MCUs in ADUM230E0BRIZ implementations.

What safety certifications apply to ADUM230E0BRIZ?

ADUM230E0BRIZ holds UL 1577 (5000 V_RMS), DIN EN IEC 60747-17 (VDE 0884-17), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1 approvals. These are documented in Tables 11 and 12 of the datasheet, with VIORM = 849 V_PEAK and reinforced insulation validated for medical and industrial safety-critical use-key for ADUM230E0BRIZ qualification in regulated end equipment.

How does ADUM230E0BRIZ compare to optocouplers in terms of lifetime reliability?

ADUM230E0BRIZ uses iCoupler® monolithic air-core transformers instead of LEDs and photodetectors, eliminating wear-out mechanisms like LED degradation and CTR drift. Its lifetime exceeds 50 years at 125°C ambient (per Analog Devices reliability reports), whereas standard optocouplers typically degrade significantly after 10–15 years-making ADUM230E0BRIZ the preferred long-lifecycle solution in infrastructure and medical ADUM230E0BRIZ deployments.

Can ADUM230E0BRIZ be used for bidirectional data isolation?

No-ADUM230E0BRIZ provides three unidirectional channels only (A, B, C inputs → A, B, C outputs). Bidirectional isolation requires separate transmit/receive pairs or devices like ADUM231E0BRIZ (which adds an enable-controlled output direction feature). The functional block diagram (Figure 2) and Truth Tables in the datasheet explicitly define ADUM230E0BRIZ as input-to-output only, confirming its unidirectional architecture.
