Product details
Overview
ADuM3210WARZ-RL7 from Analog Devices is a dual-channel, 25 Mbps digital isolator based on iCoupler® transformer technology, featuring default-low output logic, 3.3 V/5 V level translation, and reinforced insulation rated at 2500 VRMS for 1 minute. It operates from −40°C to +125°C and delivers ≤3 ns pulse width distortion at 5 V, enabling precise timing in motor drive gate interfaces and isolated SPI data converters.
For engineers reviewing the ADuM3210WARZ-RL7 datasheet, ADuM3210WARZ-RL7 pinout, ADuM3210WARZ-RL7 application, or ADuM3210WARZ-RL7 equivalent, key selection criteria include its automotive-grade 125°C operation, system-level IEC 61000-4-x ESD robustness, high common-mode transient immunity (>25 kV/µs), and dual-supply voltage translation capability across the isolation barrier.
Technical Context
The ADuM3210WARZ-RL7 implements two independent unidirectional isolation channels using monolithic air-core transformers, eliminating LED/photodiode aging and CTR drift inherent in optocouplers. Its architecture supports asymmetric supply configurations (e.g., 5 V primary / 3.3 V secondary) with guaranteed DC correctness and magnetic field immunity.
It features a refresh circuit ensuring DC signal retention during idle periods (refresh rate ≥1.1 Mbps), and incorporates layout-optimized internal structures to enhance system-level ESD performance per IEC 61000-4-2, -4-4, and -4-5 - validated under automotive-grade qualification testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 25 Mbps (NRZ); enables real-time control loop isolation in motor drives and high-speed serial interfaces like isolated RS-485. |
| Pulse Width Distortion | ≤3 ns max at 5 V; ensures minimal duty-cycle error in PWM gate drive signals and clock distribution paths. |
| Common-Mode Transient Immunity | >25 kV/µs; maintains signal integrity in noisy industrial environments with fast-switching power electronics. |
| Isolation Rating | 2500 VRMS for 1 minute (UL 1577); reinforced insulation per VDE 0884-17 (VIORM = 560 VPEAK) for functional safety compliance. |
| Operating Temperature | −40°C to +125°C; qualified for automotive battery monitoring and under-hood motor control applications. |
| Supply Voltage Range | 3.0–3.6 V or 4.5–5.5 V per side; supports mixed-voltage system interfacing without external level shifters. |
| Power Consumption | ≤7.5 mA per channel at 25 Mbps (5 V); reduces thermal load in space-constrained multichannel isolation designs. |
Pinout & Package
Narrow-body, RoHS-compliant 8-lead SOIC package (SOIC_N), 5.3 mm × 6.2 mm footprint, 1.27 mm pitch. Creepage and clearance ≥4.0 mm per IEC 60664-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Input-side power and signal inputs (VDD1, GND1, IN1, IN2) | VDD1 powers channel inputs; IN1/IN2 accept CMOS-level signals referenced to GND1; pins 1–4 form input-side isolation domain. |
| 5, 6, 7, 8 | Output-side power and signal outputs (GND2, VDD2, OUT1, OUT2) | VDD2 powers channel outputs; OUT1/OUT2 drive CMOS loads referenced to GND2; pins 5–8 form output-side isolation domain. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced system-level ESD reliability | Validated per IEC 61000-4-2 (±8 kV contact), -4-4 (±2 kV fast transient), and -4-5 (±1 kV surge) with board-level layout guidance. |
| Default-low output state | Ensures safe deactivation of downstream drivers (e.g., half-bridge gates) during power-up, brownout, or reset conditions. |
| Low propagation delay skew | ≤3 ns channel-to-channel matching (tPSKCD); critical for synchronized dual-gate drive and differential signaling integrity. |
| High-temperature operation | 125°C ambient rating with full 25 Mbps performance; eliminates derating in engine-control or traction-inverter modules. |
| Supply-independent logic thresholds | VIH = 0.7×VDDx, VIL = 0.3×VDDx; enables robust noise margin across varying supply rails and temperature extremes. |
Applications
| Motor Drive Gate Interface | SPI Isolation for Data Converters |
|---|---|
|

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-RL7 | Same package and ratings, but with default-high output logic instead of default-low. | Used where active-high enable or latch-up recovery requires asserted-on-reset behavior. | Select ADuM3211WARZ-RL7 only when system logic demands default-high assertion at power-up. |
| SI8620ED-B-IS | Capacitive isolation; 25 Mbps rated; 5 kV RMS isolation; 125°C operation; different pinout (SOIC-8W). | Lacks IEC 61000-4-x system-level ESD enhancements; lower CMTI (15 kV/µs typical). | Choose SI8620ED-B-IS only if capacitive architecture preference or alternate footprint constraints override ESD robustness requirements. |
Compared with ADuM3210WARZ-RL7, the ADuM3211WARZ-RL7 offers identical isolation and timing specs but inverted default output state, while SI8620ED-B-IS trades transformer-based ESD resilience and CMTI for capacitive integration density - making ADuM3210WARZ-RL7 optimal for automotive and industrial noise-critical gate drive and sensor interface roles.

FAQ
What is the maximum data rate supported by the ADuM3210WARZ-RL7?
The ADuM3210WARZ-RL7 supports a maximum data rate of 25 Mbps in NRZ format. This specification is guaranteed over the full operating temperature range (−40°C to +125°C) and across all supply voltage combinations (3.3 V/3.3 V, 5 V/5 V, or mixed 3.3 V/5 V). Performance is verified with CL = 15 pF and CMOS signal levels per the datasheet test conditions.
Does the ADuM3210WARZ-RL7 support level translation between different supply voltages?
Yes, the ADuM3210WARZ-RL7 supports bidirectional level translation: it operates with independent 3.0–3.6 V supplies on one side and 4.5–5.5 V on the other, enabling seamless interfacing between 3.3 V microcontrollers and 5 V peripherals or vice versa - without external level-shifting components.
What safety certifications does the ADuM3210WARZ-RL7 hold?
The ADuM3210WARZ-RL7 is certified to UL 1577 (2500 VRMS, 1 min), DIN EN IEC 60747-17 (VDE 0884-17, VIORM = 560 VPEAK), IEC/EN/CSA 62368-1, IEC/CSA 61010-1, and CQC GB4943.1. These approvals confirm reinforced insulation suitability for functional safety applications up to 600 V working voltage.
How does the default-low output behavior of the ADuM3210WARZ-RL7 improve system safety?
The ADuM3210WARZ-RL7 asserts LOW on both outputs during power-up, power-down, or input loss-of-signal conditions. This fail-safe behavior prevents unintended activation of downstream power switches (e.g., MOSFET gates), reducing risk of shoot-through faults in motor drive half-bridges and enhancing overall system reliability.
Is the ADuM3210WARZ-RL7 pin-compatible with other members of the ADuM321x family?
Yes, the ADuM3210WARZ-RL7 shares identical SOIC_N-8 pinout and footprint with ADuM3211WARZ-RL7 and all non-automotive ADuM3210 variants. However, output logic polarity differs between ADuM3210 (default-low) and ADuM3211 (default-high), so firmware or external logic must account for this inversion.
