Product details
Overview
ADUM3200WCRZ from Analog Devices is a dual-channel, automotive-grade digital isolator based on iCoupler® transformer technology, providing reinforced galvanic isolation with 2500 VRMS withstand voltage and operation up to 125°C. It supports bidirectional data transmission at up to 25 Mbps (NRZ), delivers precise timing (≤3 ns pulse width distortion, ≤3 ns channel-to-channel matching), and enables 3.3 V/5 V level translation across the isolation barrier - deployed in battery monitoring systems and isolated SPI interfaces for hybrid electric vehicles.
For engineers reviewing the ADUM3200WCRZ datasheet, ADUM3200WCRZ pinout, ADUM3200WCRZ application, or ADUM3200WCRZ equivalent, key selection criteria include its AEC-Q100 qualified automotive grade, enhanced system-level ESD reliability per IEC 61000-4-x, high common-mode transient immunity (>25 kV/µs), and compatibility with mixed-supply configurations (3.3 V/5 V or 5 V/3.3 V).
Technical Context
The ADUM3200WCRZ implements two independent unidirectional isolation channels using monolithic air-core transformers, eliminating LED/photodiode aging and nonlinearities inherent in optocouplers. Its architecture supports DC-coupled signal transmission with guaranteed DC correctness and refresh-based data retention at low or zero data rates.
It features integrated input filtering and output drivers optimized for low propagation delay skew (<15 ns typical channel matching) and stable performance across temperature (−40°C to +125°C). The device meets DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation with VIORM = 560 VPEAK and complies with UL 1577, IEC/EN/CSA 62368-1, and IEC/CSA 61010-1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 25 Mbps NRZ - supports high-speed SPI, RS-485, and digital field bus protocols without retiming. |
| Isolation Withstand Voltage | 2500 VRMS for 1 minute - meets reinforced insulation requirements for functional safety in automotive and industrial systems. |
| Pulse Width Distortion | ≤3 ns maximum - ensures minimal duty-cycle degradation for clock and PWM signals crossing the barrier. |

| Isolated RS-485 Transceiver Interface | Hybrid Electric Vehicle Inverter Control |
|
Use Scenario: Galvanically isolating half-duplex RS-485 communication between motor controller and central ECU in harsh EMI environments.

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; 5000 VRMS rating; higher CMTI (75 kV/µs); no AEC-Q100 automotive qualification. | Preferred for industrial AC/DC power supplies requiring higher isolation rating but not automotive temperature or qualification requirements. | Choose SI8620ED-B-IS when >3.75 kV RMS isolation or >50 kV/µs CMTI is mandatory, and automotive qualification is unnecessary. |
| ISO7721FDWR | Capacitive isolation; 5000 VRMS; AEC-Q100 Grade 1; lower max data rate (100 Mbps vs. 25 Mbps); higher quiescent current (1.5 mA/ch @ 0 Mbps). | Used in automotive infotainment and ADAS domains where higher bandwidth and broader automotive qualification scope are needed. | Choose ISO7721FDWR when 100 Mbps capability, extended automotive qualification coverage (e.g., ISO 26262 ASIL support), or tighter package footprint is prioritized. |
Compared with SI8620ED-B-IS and ISO7721FDWR, the ADUM3200WCRZ offers optimal balance of automotive qualification, low-power 25 Mbps operation, and proven system-level ESD resilience - making it preferred for cost-sensitive, thermally constrained HEV battery management designs where 25 Mbps suffices and 2500 VRMS meets safety architecture requirements.

FAQ
What is the maximum operating temperature of the ADUM3200WCRZ?
The ADUM3200WCRZ is rated for continuous operation from −40°C to +125°C ambient temperature and is AEC-Q100 qualified for automotive Grade 1 applications. This specification is validated per the 125°C electrical characteristics tables in the Rev. G datasheet, including supply current, propagation delay, and pulse width distortion limits under worst-case voltage and temperature conditions.
Does the ADUM3200WCRZ support bidirectional data transfer on each channel?
No - the ADUM3200WCRZ implements two unidirectional channels (INA→OUTA and INB→OUTB). Bidirectional communication requires external control logic or pairing with a complementary device like the ADUM3201WCRZ. The ADUM3200WCRZ datasheet explicitly defines pin functions and truth tables for single-direction signal flow only.
What safety certifications does the ADUM3200WCRZ hold?
The ADUM3200WCRZ is certified to UL 1577 (2500 VRMS for 1 minute), DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation (VIORM = 560 VPEAK), IEC/EN/CSA 62368-1, IEC/CSA 61010-1, and CQC GB4943.1. These certifications are documented in the Regulatory Information section of the Rev. G datasheet and verified through third-party test reports.
Can the ADUM3200WCRZ operate with different supply voltages on each side?
Yes - the ADUM3200WCRZ supports mixed-supply operation: VDD1 may be 3.3 V while VDD2 is 5 V, or vice versa. Electrical characteristics for these configurations are fully specified in Tables 7, 10, 19, and 22 of the Rev. G datasheet, covering propagation delay, supply current, and timing parameters up to 125°C.
How does the ADUM3200WCRZ differ from the standard ADUM3200CRZ?
The ADUM3200WCRZ is the automotive-grade variant with AEC-Q100 qualification (Grade 1), enhanced system-level ESD robustness per IEC 61000-4-x, and extended 125°C operation. The ADUM3200CRZ is commercial-grade (−40°C to +105°C), lacks automotive qualification, and has lower ESD hardening - confirmed by separate ordering guide entries and distinct grade markings (W vs. non-W suffix) in the datasheet's Ordering Guide table.
