Analog Devices Inc. ADUM230E1BRIZ

Overview

ADUM230E1BRIZ 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 separation between logic-level domains. It delivers 150 Mbps data rate, 13 ns max propagation delay at 5 V, and supports 1.8 V to 5 V level translation across the isolation barrier with fail-safe high output configuration.

For engineers reviewing the ADUM230E1BRIZ datasheet, ADUM230E1BRIZ pinout, ADUM230E1BRIZ application, or ADUM230E1BRIZ equivalent, this device is selected for SPI isolation, isolated data converters, and field bus interfaces where high CMTI (100 kV/µs), reinforced insulation (849 V_PEAK), and operation up to +125°C are critical design requirements.

Technical Context

The ADUM230E1BRIZ implements three independent unidirectional CMOS channels using monolithic air-core transformers, enabling dc-correct output behavior without input transitions. Its architecture ensures tight channel matching (≤3.0 ns) and low pulse width distortion (≤3 ns), making it suitable for timing-critical serial protocols.

It features dual supply domains (VDD1/VDD2), undervoltage lockout (1.5 V/1.6 V thresholds), and configurable fail-safe outputs-here set to high-state default when input power is lost or inputs disabled. Safety compliance includes UL 1577, IEC/EN/CSA 62368-1, IEC 60601-1 (2 MOPP), and DIN EN IEC 60747-17 (VDE 0884-17).

FAQ

What is the fail-safe output behavior of ADUM230E1BRIZ?

The ADUM230E1BRIZ is configured with fail-safe high output: when VDD1 is absent or DISABLE1 is asserted low, all three output channels (A/B/C) drive logic high. This behavior is fixed by the "E1" variant designation and cannot be changed via external pins or configuration. The ADUM230E1BRIZ ensures deterministic system state during power faults or initialization sequences.

Does ADUM230E1BRIZ support bidirectional data transfer?

No, ADUM230E1BRIZ implements three unidirectional channels only-A, B, and C each transmit from side 1 (input) to side 2 (output). For bidirectional isolation (e.g., I²C), separate forward/reverse channel pairs or a different part such as ADUM1250 would be required. The ADUM230E1BRIZ pinout and internal architecture do not support reverse-direction signaling on any channel.

What safety certifications apply to ADUM230E1BRIZ?

ADUM230E1BRIZ holds UL 1577 (5000 V_RMS), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), IEC/CSA 61010-1, CQC GB 4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) approvals. Its RW-16 package achieves 849 V_PEAK VIORM and 5.0 kV_RMS withstand, validated per production test at ≥1592 V_PEAK with partial discharge <5 pC.

Can ADUM230E1BRIZ operate with mismatched supply voltages on each side?

Yes, ADUM230E1BRIZ supports independent VDD1 and VDD2 supplies ranging from 1.7 V to 5.5 V each. This enables true level translation-for example, 1.8 V FPGA I/O on side 1 communicating with 5 V microcontroller peripherals on side 2. Both supplies must remain within specification; crossing outside 1.7–5.5 V risks functional failure or damage to the ADUM230E1BRIZ.

How does ADUM230E1BRIZ compare to optocouplers in terms of timing performance?

ADUM230E1BRIZ offers 13 ns max propagation delay and ≤3 ns pulse width distortion-over 10× faster and significantly more consistent than typical optocouplers (which often exceed 100 ns delay with >20 ns skew). Unlike optocouplers, the ADUM230E1BRIZ maintains dc correctness and stable timing across temperature and lifetime, with no LED degradation or bias-current drift affecting the ADUM230E1BRIZ's signal fidelity.
