Product details
Overview
ADUM3200BRZ from Analog Devices is a dual-channel, bidirectional digital isolator based on iCoupler® transformer technology, providing 2500 VRMS galvanic isolation with 25 Mbps data rate, 3 ns pulse width distortion, and operation at 3.3 V or 5 V supply rails. It enables level translation between isolated domains and supports SPI, RS-485, and battery monitor interfaces in automotive and industrial systems.
For engineers reviewing the ADUM3200BRZ datasheet, ADUM3200BRZ pinout, ADUM3200BRZ application, or ADUM3200BRZ equivalent, this page delivers verified specifications, package mapping, functional pin roles, real-world use cases, and validated alternative options for system-level ESD-critical isolation designs.
Technical Context
The ADUM3200BRZ implements two independent unidirectional isolation channels using monolithic air-core transformers, eliminating LED/photodiode aging and CTR drift. Its architecture supports mixed-voltage operation (3.3 V/5 V across isolation barrier) and guarantees precise timing with ≤3 ns pulse width distortion and ≤3 ns channel-to-channel matching.
It achieves >25 kV/µs common-mode transient immunity via differential signaling and optimized layout, and meets IEC/EN/CSA 62368-1, UL 1577, and DIN EN IEC 60747-17 (VDE 0884-17) safety standards with VIORM = 560 VPEAK and VISO = 2500 VRMS for 1 minute.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8620ED-B-IS | Capacitive isolation; 25 Mbps max; 3.75 kVRMS rating; no automotive grade option. | Lacks AEC-Q100 qualification and 125°C extended temperature support. | Preferred where cost sensitivity outweighs automotive qualification and long-term reliability under thermal stress. |
| ISO7720D | Capacitive isolation; 100 Mbps max; 5000 VRMS rating; higher power consumption at 25 Mbps. | Higher speed margin but consumes ~2× more current than ADUM3200BRZ at 25 Mbps (10.0 mA vs. 4.9 mA). | Chosen when future-proofing for >25 Mbps upgrades is prioritized over quiescent power and thermal design simplicity. |
Compared with SI8620ED-B-IS and ISO7720D, the ADUM3200BRZ delivers optimal balance of automotive-grade reliability, ultra-low timing skew, and sub-5 mA active current at 25 Mbps-making it ideal for thermally constrained, safety-critical isolation where precision timing and long service life are mandatory.

FAQ
What is the maximum data rate supported by ADUM3200BRZ?
The ADUM3200BRZ supports a maximum data rate of 25 Mbps in NRZ format, verified across all operating conditions including 125°C ambient and mixed 3.3 V/5 V supply configurations. This rating applies to both channels simultaneously and is guaranteed with ≤3 ns pulse width distortion, enabling reliable high-speed SPI and digital control link implementation.
Does ADUM3200BRZ support level translation between different supply voltages?
Yes, ADUM3200BRZ supports true bidirectional level translation: VDD1 and VDD2 can operate independently at either 3.3 V (3.0–3.6 V) or 5 V (4.5–5.5 V), allowing seamless interfacing between 3.3 V MCUs and 5 V peripherals-or vice versa-without external level-shifting circuitry.
What safety certifications does ADUM3200BRZ hold?
ADUM3200BRZ is certified to UL 1577 (2500 VRMS for 1 minute), IEC/EN/CSA 62368-1, IEC/CSA 61010-1, CQC GB4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 560 VPEAK. These approvals validate its suitability for reinforced insulation in industrial and automotive end equipment.
Is ADUM3200BRZ qualified for automotive applications?
Yes, ADUM3200BRZ is AEC-Q100 qualified (Grade 0/1) and specified for continuous operation from −40°C to +125°C. Its enhanced system-level ESD reliability per IEC 61000-4-x and robust CMTI (>25 kV/µs) make it suitable for hybrid electric vehicle battery monitors, onboard chargers, and powertrain control units.
How does ADUM3200BRZ differ from optocouplers in terms of reliability and power use?
ADUM3200BRZ uses iCoupler® transformer isolation instead of LEDs and photodiodes, eliminating CTR degradation, nonlinear transfer, and temperature-dependent aging. It consumes one-tenth to one-sixth the power of comparable optocouplers at 25 Mbps-e.g., 4.9 mA total at 25 Mbps versus >30 mA for high-speed optos-reducing thermal design burden and improving long-term stability.
