Product details
Overview
ADUM3200WARZ from Analog Devices is a dual-channel, reinforced digital isolator based on iCoupler® transformer technology, designed for bidirectional signal isolation across high-voltage barriers in industrial and automotive systems. It supports 3.3 V or 5 V supplies on either side, delivers up to 25 Mbps data rate, achieves ≤3 ns pulse width distortion, and operates reliably at 125°C ambient temperature - enabling use in battery monitor interfaces and isolated SPI buses.
For engineers reviewing the ADUM3200WARZ datasheet, ADUM3200WARZ pinout, ADUM3200WARZ application, or ADUM3200WARZ equivalent, this page provides verified specifications, package mapping, functional role in level-translating isolation chains, ESD-enhanced system-level reliability per IEC 61000-4-x, and validated alternative options for automotive-grade dual-channel isolation.
Technical Context
The ADUM3200WARZ implements two independent unidirectional isolation channels using monolithic air-core transformers, eliminating LED/photodiode aging and CTR drift inherent in optocouplers. Its architecture enables precise timing control with ≤3 ns channel-to-channel matching and ≤3 ns pulse width distortion across all supply configurations (3.3 V/3.3 V, 5 V/5 V, or mixed 3.3 V/5 V).
It integrates refresh circuitry to maintain DC correctness during idle periods and features enhanced layout-aware ESD robustness per IEC 61000-4-2/4/5, validated under automotive-grade thermal stress (−40°C to +125°C) and qualified to DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 560 VPEAK and VISO = 2500 VRMS for 1 minute.

FAQ
What is the maximum data rate supported by the ADUM3200WARZ?
The ADUM3200WARZ supports a maximum data rate of 25 Mbps in NRZ format across all supply configurations (3.3 V/3.3 V, 5 V/5 V, or mixed). This is confirmed in Tables 1, 4, 7, 10, 13, 16, 19, and 22 of the Rev. G datasheet, with timing validated up to 125°C ambient. The ADUM3200WARZ maintains signal integrity at this rate due to ≤3 ns pulse width distortion and ≤2.5 ns rise/fall times.
Does the ADUM3200WARZ support level translation between 3.3 V and 5 V domains?
Yes, the ADUM3200WARZ fully supports bidirectional level translation: VDD1 and VDD2 may be independently set to 3.3 V or 5 V. Electrical characteristics for mixed-supply operation (e.g., VDD1 = 5 V / VDD2 = 3.3 V) are explicitly specified in Tables 7–8 and 19–20, confirming compatible logic thresholds, VOH/VOL levels, and timing performance at 25 Mbps.
What safety certifications does the ADUM3200WARZ hold?
The ADUM3200WARZ is certified to UL 1577 (VISO = 2500 VRMS for 1 minute), DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 560 VPEAK, IEC/EN/CSA 62368-1, IEC/CSA 61010-1, and CQC GB4943.1. These are listed in the Regulatory Information section (page 13) and Insulation and Safety-Related Specifications (page 13) of the Rev. G datasheet.
How does the ADUM3200WARZ differ from standard ADUM3200 variants?
The "W" suffix in ADUM3200WARZ denotes automotive qualification: it is rated for −40°C to +125°C operation and tested per AEC-Q100 Grade 1. The "ARZ" package code specifies the narrow-body SOIC_N-8 variant. Unlike commercial-grade ADUM3200ARZ, the ADUM3200WARZ includes enhanced system-level ESD robustness per IEC 61000-4-x, verified in AN-793.
What is the common-mode transient immunity (CMTI) specification for ADUM3200WARZ?
The ADUM3200WARZ guarantees >25 kV/µs common-mode transient immunity, with typical performance up to 35 kV/µs. This value is specified in Tables 3, 6, 9, 12, 15, 18, 21, and 24 across all supply and temperature conditions, and applies to both rising and falling edges per footnote 1 in the datasheet.
