Product details

Overview

ADUM230D0BRIZ from Analog Devices is a triple-channel, 5.0 kV_RMS digital isolator using iCoupler® technology, designed for high-noise industrial interfaces. It delivers 150 Mbps data rate, 13 ns max propagation delay at 5 V, and 1.8 V to 5 V level translation across the isolation barrier. It is used in SPI isolation for motor control feedback loops where galvanic separation and timing integrity are critical.

For engineers reviewing the ADUM230D0BRIZ datasheet, ADUM230D0BRIZ pinout, ADUM230D0BRIZ application, or ADUM230D0BRIZ equivalent, this page provides verified specifications, fail-safe output behavior, safety certifications (UL 1577, VDE 0884-17), SOIC-16 package details, and real-world use context for industrial field bus and data converter isolation.

Technical Context

The ADUM230D0BRIZ implements three independent unidirectional CMOS-isolated channels with air-core transformer coupling. Its architecture ensures dc-correct output states without input transitions and supports two fail-safe modes-high or low-activated during input-side power loss or disable.

It operates across dual supply rails (VDD1/VDD2) from 1.7 V to 5.5 V, enabling bidirectional voltage translation. With 100 kV/µs common-mode transient immunity and ≤3 ns channel matching, it maintains signal fidelity in high-dv/dt environments such as inverters and PLC I/O modules.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SI8630BB-B-IS	3-channel, 5 kV_RMS, 150 Mbps, but uses capacitive isolation and lacks 1.8 V operation	Lower CMTI (75 kV/µs); not rated for 1.8 V side; requires external level shifters below 2.5 V	Choose for cost-sensitive, non-ultra-low-voltage designs where capacitive isolation suffices
ISO6731FDWR	3-channel, 5 kV_RMS	Higher quiescent current (3.5 mA/side vs. 2.6 mA), no fail-safe output configuration	Choose when TI ecosystem integration or enhanced ESD robustness (±12 kV HBM) is prioritized over fail-safe determinism

Compared with SI8630BB-B-IS and ISO6731FDWR, ADUM230D0BRIZ uniquely combines 1.8 V compatibility, programmable fail-safe outputs, and 100 kV/µs CMTI - making it optimal for next-generation industrial controllers requiring both ultra-low-power operation and deterministic safety behavior.

FAQ

What is the maximum guaranteed data rate for ADUM230D0BRIZ?

The ADUM230D0BRIZ guarantees a maximum data rate of 150 Mbps across its full operating temperature and voltage range. This rating is validated per the datasheet's switching specifications table and applies to all three channels simultaneously with pulse width distortion maintained within 3 ns. Higher speeds may be achievable in specific conditions but are not production-guaranteed.

Does ADUM230D0BRIZ support 1.8 V operation on both sides?

Yes, ADUM230D0BRIZ supports independent 1.8 V operation on both VDD1 and VDD2 supplies. The datasheet specifies full functionality-including 150 Mbps data rate and 15 ns max propagation delay-at 1.8 V, with input thresholds scaling to 0.3×VDD and 0.7×VDD. This enables direct interfacing with ultra-low-voltage microcontrollers without level-shifting circuitry.

What safety certifications does ADUM230D0BRIZ hold?

ADUM230D0BRIZ holds UL 1577 (5000 V_RMS, 1 min), DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation (849 V_PEAK), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1. These certifications are verified per package type RW-16 and apply to the ADUM230D0BRIZ variant specifically.

How does the fail-safe output function work on ADUM230D0BRIZ?

The ADUM230D0BRIZ offers user-selectable fail-safe output states (high or low) activated when the input-side supply (VDD1) is absent or when DISABLE1 is asserted. This behavior is implemented in hardware and does not require configuration registers. For ADUM230D0BRIZ, the default fail-safe state is low - ensuring outputs settle to logic 0 during power loss or disable events.

What is the creepage and clearance distance of the ADUM230D0BRIZ SOIC package?

The ADUM230D0BRIZ uses the RW-16 wide-body SOIC package with minimum external creepage and clearance distances of 8.3 mm between input and output pins, measured per IEC 62368-1 guidelines for pollution degree 2 and altitudes ≤2000 m. These values are validated for reinforced insulation and support 2 MOPP in medical applications.
