Product details
Overview
ADuM3210WARZ from Analog Devices is a dual-channel, reinforced digital isolator based on iCoupler® transformer technology, delivering 25 Mbps data rate, 3 ns pulse width distortion at 5 V, and 25 kV/µs common-mode transient immunity. It features default-low output logic, operates from 3.3 V or 5 V supplies on either side, and supports level translation - used in SPI isolation, motor drive gate interfaces, and battery monitor systems requiring high ESD reliability.
For engineers reviewing the ADuM3210WARZ datasheet, ADuM3210WARZ pinout, ADuM3210WARZ application, or ADuM3210WARZ equivalent, this page provides verified specifications, automotive-grade thermal performance up to 125°C, safety certifications (UL 1577, VDE 0884-17), and real-world design context for industrial and automotive isolation circuits.
Technical Context
The ADuM3210WARZ implements two independent unidirectional isolation channels using monolithic air-core transformers, eliminating LED aging and CTR drift inherent in optocouplers. Its architecture enables precise timing control with ≤3 ns pulse width distortion and ≤3 ns channel-to-channel matching under 5 V operation.
It supports mixed-voltage operation (3.3 V/5 V or 5 V/3.3 V across isolation barrier), delivers reinforced insulation rated at 2500 VRMS (1 min) and 560 VPEAK per VDE 0884-17, and is qualified for automotive applications with guaranteed operation from −40°C to +125°C.

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 |
|---|---|---|---|
| ADUM3211WARZ | Same package and specs, but with default-high output logic instead of default-low. | Required where upstream logic expects active-high enable or reset assertion on power-up. | Select ADUM3211WARZ only when system-level power-on behavior mandates high-default outputs. |
| SI8620ED-B-IS | Capacitive isolation; 25 Mbps rated; 3.75 kVRMS isolation; no VDE 0884-17 reinforced rating. | Lacks reinforced certification for automotive battery systems; suitable for industrial RS-485 where basic insulation suffices. | Choose SI8620ED-B-IS for cost-sensitive non-automotive designs needing similar speed but not VDE-reinforced compliance. |
Compared with ADUM3210WARZ, ADUM3211WARZ offers identical timing and safety specs but inverted power-on state, while SI8620ED-B-IS trades VDE-reinforced certification for lower unit cost in non-safety-critical applications - selection depends on startup logic requirements and regulatory scope.

FAQ
What is the maximum data rate supported by the ADuM3210WARZ?
The ADuM3210WARZ supports a maximum data rate of 25 Mbps in NRZ format. This is confirmed across all operating conditions - including 3.3 V/3.3 V, 5 V/5 V, and mixed-supply configurations - and is validated up to 125°C ambient temperature per the Rev. L datasheet Table 13 and Table 16. The ADuM3210WARZ maintains signal integrity at this rate due to its low pulse width distortion and high common-mode transient immunity.
Does the ADuM3210WARZ support level translation between different supply voltages?
Yes, the ADuM3210WARZ supports true bidirectional level translation: it operates with 3.3 V on one side and 5 V on the other (either VDD1 = 3.3 V / VDD2 = 5 V or vice versa). Electrical characteristics - including propagation delay, PWD, and supply current - are fully specified for these mixed-voltage modes in Tables 7, 10, 19, and 22 of the datasheet. This eliminates the need for external level-shifting components in mixed-voltage systems.
What safety certifications does the ADuM3210WARZ hold?
The ADuM3210WARZ holds UL 1577 (2500 VRMS, 1 minute), DIN EN IEC 60747-17 (VDE 0884-17) reinforced insulation (560 VPEAK), IEC/EN/CSA 62368-1, and IEC/CSA 61010-1 certifications. These are explicitly listed in Table 26 of the datasheet and apply to the WARZ variant. The "W" suffix denotes automotive qualification, and the "ARZ" packaging confirms SOIC_N with VDE 0884-17 compliance.
How does the ADuM3210WARZ differ from the ADuM3200 series?
The ADuM3210WARZ differs from the ADuM3200 series primarily in its default output state (low vs. high) and enhanced system-level ESD robustness. Per the General Description section, ADuM3210/ADuM3211 include circuit and layout improvements that increase immunity to IEC 61000-4-x ESD, burst, and surge events. The ADuM3210WARZ also features automotive qualification (125°C operation), whereas standard ADuM3200 variants are rated to 105°C.
What is the power consumption of the ADuM3210WARZ at 10 Mbps operation?
At 10 Mbps, the ADuM3210WARZ consumes 4.8 mA per channel on the input side (IDD1) and 2.8 mA per channel on the output side (IDD2) when operating at 5 V/5 V, as specified in Table 2 of the datasheet. Under 3.3 V/3.3 V conditions at 10 Mbps, consumption drops to 3.2 mA (IDD1) and 1.9 mA (IDD2) per channel - values confirmed for the WA/WB/WC automotive grades in Tables 14 and 17.
