Analog Devices Inc. ADUM230D0BRWZ

Overview

ADUM230D0BRWZ 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 supports 1.8 V to 5 V level translation across the isolation barrier. It is used in SPI isolation for motor drives requiring reinforced insulation and fail-safe operation.

For engineers reviewing the ADUM230D0BRWZ datasheet, ADUM230D0BRWZ pinout, ADUM230D0BRWZ application, or ADUM230D0BRWZ equivalent, key selection criteria include reinforced 5.0 kV_RMS isolation rating, 100 kV/µs common-mode transient immunity, fail-safe high output configuration, SOIC-16 wide-body package, and compliance with IEC/EN/CSA 62368-1 and DIN EN IEC 60747-17 (VDE 0884-17).

Technical Context

The ADUM230D0BRWZ implements three independent unidirectional CMOS-isolated 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), critical for timing-sensitive serial protocols.

It features dual supply domains (VDD1/VDD2), each operable from 1.7 V to 5.5 V, allowing asymmetric voltage translation (e.g., 1.8 V logic side to 3.3 V MCU side). Fail-safe logic is implemented via internal circuitry that forces outputs high when input power is absent or DISABLE1 is asserted.

FAQ

What is the isolation voltage rating of ADUM230D0BRWZ and which safety standards does it meet?

ADUM230D0BRWZ has a 5.0 kV_RMS isolation rating for 1 minute per UL 1577 and achieves reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 849 V_PEAK. It is certified to IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1. These ratings are validated on the RW-16 wide-body SOIC package used by ADUM230D0BRWZ.

Does ADUM230D0BRWZ support level translation between different supply voltages?

Yes, ADUM230D0BRWZ supports true bidirectional level translation: VDD1 and VDD2 operate independently from 1.7 V to 5.5 V, enabling interfaces such as 1.8 V FPGA to 5 V DAC or 3.3 V MCU to 2.5 V sensor. Input thresholds scale with respective VDD (VIH = 0.7×VDDx), and outputs swing rail-to-rail relative to their VDDx, making ADUM230D0BRWZ ideal for mixed-voltage system isolation.

What is the fail-safe behavior of ADUM230D0BRWZ and how is it activated?

ADUM230D0BRWZ is a D0 variant with fail-safe high output: when VDD1 is unpowered or DISABLE1 is driven high, all three outputs (OUTA/B/C) transition to and hold logic high. This behavior is intrinsic to the ADUM230D0BRWZ silicon design and requires no external components. It ensures defined states during power sequencing or fault conditions-critical in motor control and safety interlock circuits.

Can ADUM230D0BRWZ be used in medical applications requiring 2 MOPP?

Yes, ADUM230D0BRWZ is certified to IEC/CSA 60601-1 for 2 Means of Patient Protection (2 MOPP) with reinforced insulation, verified under DIN EN IEC 60747-17 test conditions. Its RW-16 package provides 8.3 mm creepage/clearance and 849 V_PEAK VIORM, satisfying the stringent isolation requirements of patient-connected devices-making ADUM230D0BRWZ suitable for ECG monitors, infusion pumps, and diagnostic imaging subsystems.

What is the maximum data rate supported by ADUM230D0BRWZ and what timing parameters guarantee its reliability at that rate?

ADUM230D0BRWZ supports up to 150 Mbps with guaranteed timing performance: max propagation delay is 13 ns (5 V), pulse width distortion ≤3 ns, and channel matching ≤3.0 ns. These specs ensure robust eye opening at full rate under worst-case voltage/temperature conditions. The 150 Mbps limit reflects tested performance-not theoretical maximum-and applies across the full −40°C to +125°C operating range for ADUM230D0BRWZ.
