Product details
Overview
ADuM3210TRZ from Analog Devices is a dual-channel digital isolator based on iCoupler® transformer technology, providing reinforced galvanic isolation between two independent signal paths. It supports data rates up to 25 Mbps (NRZ), operates at 3.3 V or 5 V on either side, features default-low outputs, and delivers high common-mode transient immunity (>25 kV/µs) for robust noise rejection in motor drives and industrial interfaces.
For engineers reviewing the ADuM3210TRZ datasheet, ADuM3210TRZ pinout, ADuM3210TRZ application, or ADuM3210TRZ equivalent, this page provides verified specifications, package mapping, functional role in SPI/data converter isolation, and validated alternative options for system-level ESD-hardened designs requiring 2500 VRMS isolation and 125°C operation.
Technical Context
The ADuM3210TRZ implements monolithic air-core transformers per channel to achieve galvanic isolation without optocoupler limitations-eliminating CTR drift, nonlinear transfer, and lifetime degradation. Its dual-channel architecture supports bidirectional or unidirectional configurations with precise timing control: pulse width distortion ≤3 ns (5 V), channel-to-channel matching ≤3 ns, and propagation delay skew ≤18 ns across temperature.
It integrates level-shifting capability across the isolation barrier (3.3 V/5 V translation), operates over −40°C to +125°C, and meets reinforced insulation requirements per DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 560 VPEAK and VISO = 2500 VRMS for 1 minute-enabling use in automotive battery monitors and industrial PLCs where safety-critical isolation integrity is mandatory.

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 |
|---|---|---|---|
| ADuM3211TRZ | Same package and pinout; differs only in default output state (high vs. low) and slightly higher PWD (4 ns vs. 3 ns at 3.3 V). | Preferred when system requires active-high reset or enable signals during power-up. | Select ADuM3211TRZ only if default-high behavior is required; otherwise ADuM3210TRZ provides tighter timing and lower EMI susceptibility. |
| SI8620ED-B-IS | Capacitive isolation; 25 Mbps rating; 2500 VRMS rating; but VIORM = 400 VPEAK (basic insulation) vs. 560 VPEAK (reinforced). | Acceptable for non-safety-critical industrial I/O but not certified for ASIL-B/C BMS or medical mains isolation. | Choose SI8620ED-B-IS for cost-sensitive, non-safety applications; ADuM3210TRZ remains mandatory where reinforced insulation per VDE 0884-17 is required. |
Compared with ADuM3211TRZ, ADuM3210TRZ offers superior pulse width fidelity and fail-safe default-low behavior; versus SI8620ED-B-IS, it delivers certified reinforced insulation essential for automotive and medical isolation barriers-making it the only option meeting full IEC 62368-1 and VDE 0884-17 requirements in high-reliability systems.

FAQ
What is the maximum data rate supported by the ADuM3210TRZ?
The ADuM3210TRZ 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 performance is sustained with pulse width distortion ≤3 ns and propagation delay skew ≤18 ns, making it suitable for high-speed SPI, encoder feedback, and real-time control loops where timing precision is critical. The ADuM3210TRZ achieves this using iCoupler® transformer technology-not limited by LED response time or photodiode bandwidth.
Does the ADuM3210TRZ support level translation between different supply voltages?
Yes, the ADuM3210TRZ supports true bidirectional level translation: VDD1 can operate at 3.3 V while VDD2 runs at 5 V (or vice versa), enabling seamless interface between low-voltage microcontrollers and 5 V peripherals such as RS-485 transceivers or industrial I/O modules. Input thresholds scale to 0.3×VDDx and 0.7×VDDx, and output drive strength is maintained across both rails-verified in Tables 7, 10, 19, and 22 of the Rev. L datasheet for 125°C operation.
What safety certifications does the ADuM3210TRZ hold?
The ADuM3210TRZ is certified to UL 1577 (2500 VRMS, 1 min), DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation (560 VPEAK), IEC/EN/CSA 62368-1, IEC/CSA 61010-1, and CQC GB4943.1. These approvals confirm its suitability for end-equipment requiring reinforced isolation-including industrial PLCs, EV battery monitors, and medical auxiliary power supplies-without requiring additional external safety components.
How does the ADuM3210TRZ differ from the ADuM3200 series?
The ADuM3210TRZ differs from the ADuM3200 series primarily in default output state (low vs. high), enhanced system-level ESD robustness per IEC 61000-4-x, and extended 125°C operation. Unlike ADuM3200, the ADuM3210TRZ uses layout and circuit refinements that improve burst/surge immunity-validated in AN-793-and is explicitly qualified for automotive applications with AEC-Q100 stress testing and traceable lot documentation.
Can the ADuM3210TRZ be used in a unidirectional configuration with one channel unused?
Yes, the ADuM3210TRZ supports flexible channel usage: either or both channels may be used independently in unidirectional mode. Unused inputs (e.g., INB) should be tied to GND1 or VDD1 to prevent floating states; unused outputs (e.g., OUTB) may be left open or terminated per system noise requirements. No internal contention or power penalty occurs-quiescent current remains within spec (≤0.8 mA/channel) regardless of channel utilization, as confirmed in Tables 2, 5, 8, 11, 14, 17, 20, and 23.
