Product details
Overview
ADUM3200WBRZ from Analog Devices is a dual-channel, bidirectional digital isolator based on iCoupler® transformer technology, delivering 25 Mbps data rate, 3 ns pulse width distortion, and 25 kV/µs common-mode transient immunity. It operates at 3.3 V or 5 V on either side, supports level translation, and is qualified for automotive use up to 125°C in narrow-body SOIC-8 packaging.
For engineers reviewing the ADUM3200WBRZ datasheet, ADUM3200WBRZ pinout, ADUM3200WBRZ application, or ADUM3200WBRZ equivalent, this page provides verified specifications, automotive-grade isolation performance, precise timing parameters, and validated alternative options for SPI, RS-485, and battery monitoring systems.
Technical Context
The ADUM3200WBRZ implements two independent galvanic isolation channels using monolithic air-core transformers, eliminating LED/photodiode aging and CTR drift inherent in optocouplers. Its architecture enables deterministic propagation delay (≤45 ns max at 25 Mbps, 125°C) and channel-to-channel matching (≤3 ns).
It features enhanced system-level ESD robustness per IEC 61000-4-x, reinforced insulation rated at VISO = 2500 VRMS (1 min) and VIORM = 560 VPEAK, and meets DIN EN IEC 60747-17 (VDE 0884-17), IEC/EN/CSA 62368-1, and IEC/CSA 61010-1 safety standards.

FAQ
What is the maximum data rate supported by ADUM3200WBRZ?
The ADUM3200WBRZ supports a maximum data rate of 25 Mbps in NRZ format across its dual channels. This is validated over the full −40°C to +125°C temperature range and at both 3.3 V and 5 V supply configurations. The device maintains timing integrity up to this rate, with pulse width distortion capped at 3 ns and propagation delay skew ≤3 ns between channels - critical for high-speed SPI and isolated serial interfaces.
Does ADUM3200WBRZ support level translation between 3.3 V and 5 V domains?
Yes, ADUM3200WBRZ supports true bidirectional level translation: VDD1 and VDD2 can be independently set to 3.3 V or 5 V (within 3.0–3.6 V or 4.5–5.5 V ranges). This allows seamless interfacing between 3.3 V microcontrollers and 5 V analog front-ends or transceivers without external level shifters - a key feature confirmed in Tables 7, 10, 19, and 22 of the Rev. G datasheet.
Is ADUM3200WBRZ qualified for automotive applications?
Yes, ADUM3200WBRZ is an automotive-grade variant (denoted by "W" suffix) qualified per AEC-Q100 standards for operation from −40°C to +125°C. It is explicitly listed in the "Automotive Products" section (p. 24) of the datasheet and carries enhanced system-level ESD robustness per IEC 61000-4-x - making it suitable for battery monitors, inverter controls, and other ASIL-B–capable systems.
What safety certifications does ADUM3200WBRZ hold?
ADUM3200WBRZ is certified to UL 1577 (2500 VRMS, 1 min), DIN EN IEC 60747-17 (VDE 0884-17), IEC/EN/CSA 62368-1, IEC/CSA 61010-1, and CQC GB4943.1. Its VIORM rating is 560 VPEAK, confirming reinforced insulation capability. These certifications are detailed in the "Regulatory Information" and "Insulation and Safety-Related Specifications" sections (pp. 13–14) of the datasheet.
How does ADUM3200WBRZ differ from the standard ADUM3200BRZ?
The ADUM3200WBRZ is the automotive-qualified version of the ADUM3200BRZ, featuring WA/WB/WC grade screening for 125°C operation, enhanced system-level ESD robustness per IEC 61000-4-x, and full AEC-Q100 compliance. Electrical specs (e.g., 25 Mbps, 3 ns PWD) are identical, but the "W" variant undergoes additional automotive-specific reliability testing and lot traceability - essential for Tier 1 automotive supply chains.
