Analog Devices Inc. ADUM130D1BRWZ

Overview

ADUM130D1BRWZ from Analog Devices is a triple-channel digital isolator based on iCoupler® transformer technology, providing reinforced galvanic isolation for high-noise industrial interfaces. It delivers 150 Mbps data rate, 13 ns max propagation delay at 5 V, 100 kV/µs common-mode transient immunity, and operates across 1.8 V to 5 V supply rails. It is used in SPI isolation between microcontrollers and isolated ADCs in motor drive control systems.

For engineers reviewing the ADUM130D1BRWZ datasheet, ADUM130D1BRWZ pinout, ADUM130D1BRWZ application, or ADUM130D1BRWZ equivalent, key selection criteria include its 3.75 kV_RMS isolation rating (RW-16 SOIC_W package), fail-safe high output option, and compatibility with 1.8 V–5 V level translation across the barrier.

Technical Context

The ADUM130D1BRWZ implements three independent unidirectional CMOS-isolated channels using monolithic air-core transformers and integrated DC-correcting logic. Its architecture ensures dc correctness without input transitions and supports configurable fail-safe output states (high or low) during power loss or disable conditions.

It features tight channel matching (≤3.0 ns codirectional skew), low jitter (90 ps rms at 1.8 V), and robust noise rejection via differential transformer coupling and high CMTI (100 kV/µs). The device complies with DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation and meets IEC 60601-1 (2 MOPP) requirements.

FAQ

What is the maximum guaranteed data rate for ADUM130D1BRWZ?

The ADUM130D1BRWZ has a maximum guaranteed data rate of 150 Mbps, validated across all operating voltages (1.8 V to 5 V) and temperatures (−40°C to +125°C). This rate ensures reliable SPI communication with timing margin for clock-to-data setup/hold, and is supported by pulse width distortion ≤3 ns and jitter as low as 90 ps rms at 1.8 V operation. Higher rates may be achievable but are not production-guaranteed.

Does ADUM130D1BRWZ support level translation between different supply voltages?

Yes, ADUM130D1BRWZ supports true bidirectional level translation: VDD1 and VDD2 can each operate independently from 1.8 V to 5 V. For example, it can translate 1.8 V logic from an ultra-low-power MCU to 3.3 V or 5 V peripherals on the isolated side, preserving signal integrity without external level shifters. Input thresholds scale with VDDx (VIH = 0.7×VDDx), and outputs swing rail-to-rail within their respective supply domains.

What safety certifications apply to ADUM130D1BRWZ?

ADUM130D1BRWZ in the RW-16 package is certified to UL 1577 (3750 V_RMS), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), IEC/CSA 61010-1, and DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation. It carries the * marking denoting VDE 0884-17 compliance, and achieves VIORM = 849 V_PEAK and working voltage VIOWM = 760 V_RMS per IEC 60664-1 Category III.

How does the fail-safe output behavior work on ADUM130D1BRWZ?

ADUM130D1BRWZ defaults to fail-safe high output: when VDD1 is unpowered, DISABLE1 is asserted, or VE2 is deasserted, all three outputs (OUTA/B/C) drive high. This behavior is hardwired and requires no external components. It ensures predictable system state during power sequencing faults or controller resets-critical in safety-rated motor control and medical power systems where undefined logic levels could trigger hazardous conditions.

What is the thermal performance of ADUM130D1BRWZ in the RW-16 package?

ADUM130D1BRWZ in the RW-16 SOIC_W package has a junction-to-ambient thermal resistance (θ_JA) of 45°C/W, measured with thermocouple at package underside center. At full 150 Mbps operation and 5 V supplies, total power dissipation remains below 1.64 W (per safety limit), enabling reliable operation up to +125°C junction temperature. PCB layout with ≥2 cm² copper pour under the package further reduces thermal impedance in high-density industrial designs.
