Product details
Overview
ADuM3210TRZ-RL7 from Analog Devices is a dual-channel digital isolator based on iCoupler® transformer technology, providing reinforced galvanic isolation for signal integrity across high-noise industrial and automotive interfaces. It delivers 25 Mbps data rate, 3 ns pulse width distortion at 5 V, and operates from 3.3 V or 5 V supplies with default-low output logic - used in isolated SPI, RS-485 transceivers, and motor drive gate control.
For engineers reviewing the ADuM3210TRZ-RL7 datasheet, ADuM3210TRZ-RL7 pinout, ADuM3210TRZ-RL7 application, or ADuM3210TRZ-RL7 equivalent, key selection criteria include its 2500 VRMS isolation rating, 125°C automotive qualification, precise channel-to-channel matching (≤3 ns), and mixed-voltage level translation capability between 3.3 V and 5 V domains.
Technical Context
The ADuM3210TRZ-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 both same-side and cross-supply operation (e.g., VDD1 = 5 V, VDD2 = 3.3 V), enabling voltage-level translation without external level shifters.
It features enhanced system-level ESD robustness per IEC 61000-4-x, >25 kV/µs common-mode transient immunity, and guaranteed operation up to +125°C. The device uses a narrow-body 8-lead SOIC package with reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17) and UL 1577 certification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 25 Mbps (NRZ) - supports high-speed serial protocols like isolated SPI and CAN FD physical layer signaling. |
| Isolation Rating | 2500 VRMS for 1 minute (UL 1577); 560 VPEAK reinforced (VDE 0884-17) - enables safe interface between hazardous and non-hazardous zones. |
| Pulse Width Distortion | ≤3 ns max at 5 V - ensures minimal duty-cycle degradation in PWM or clock distribution applications. |
| Channel Matching | ≤3 ns max codirectional skew - critical for time-sensitive dual-signal paths such as isolated ADC synchronization. |
| Supply Voltage Range | 3.0–3.6 V or 4.5–5.5 V per side - allows flexible integration into mixed-voltage systems without level-shifting circuitry. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, battery management, and industrial motor control environments. |
| Power Consumption | 1.7 mA/channel @ 2 Mbps (5 V); 1.5 mA/channel @ 2 Mbps (3.3 V) - reduces thermal load in space-constrained modules. |

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-RL7 | Same package and pinout; differs only in default output state (ADuM3211 is default-high). | Required where active-high enable or logic polarity matching is mandatory (e.g., certain MCU GPIO wake-up schemes). | Select ADuM3211TRZ-RL7 only if system-level logic requires default-high outputs; otherwise ADuM3210TRZ-RL7 provides superior fail-safe behavior in gate drive contexts. |
| SI8620ED-B-IS | Capacitive isolation; 25 Mbps rated; 3.75 kVRMS isolation; 5000 VRMS surge rating; different pinout (SOIC-8 but non-compatible mapping). | Better surge immunity (5 kVRMS), but lacks VDE 0884-17 reinforced certification and automotive qualification. | Prefer SI8620ED-B-IS for cost-sensitive industrial applications requiring higher surge tolerance; avoid where VDE-reinforced certification or 125°C operation is mandatory. |
Compared with ADuM3211TRZ-RL7, ADuM3210TRZ-RL7 offers safer default-low behavior for fault-tolerant gate driving; compared with SI8620ED-B-IS, it provides certified reinforced insulation and guaranteed 125°C operation - making it the only choice for ASIL-B automotive BMS and industrial inverters requiring long-term reliability under thermal stress.

FAQ
What is the maximum data rate supported by ADuM3210TRZ-RL7?
The ADuM3210TRZ-RL7 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 enables use in high-speed isolated serial interfaces such as SPI, RS-422, and digital encoder feedback links without timing degradation.
Does ADuM3210TRZ-RL7 support level translation between 3.3 V and 5 V domains?
Yes, ADuM3210TRZ-RL7 fully supports bidirectional level translation: VDD1 may be 3.3 V while VDD2 is 5 V, or vice versa. This eliminates external level shifters in mixed-voltage systems - for example, isolating a 3.3 V microcontroller from a 5 V RS-485 transceiver while maintaining signal integrity and timing accuracy.
What safety certifications does ADuM3210TRZ-RL7 hold?
ADuM3210TRZ-RL7 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, and IEC/CSA 61010-1. These approvals validate its suitability for functional safety applications in industrial and automotive systems up to CAT III environments.
How does the default-low output behavior of ADuM3210TRZ-RL7 improve system safety?
The default-low output ensures that both OUTA and OUTB remain logically low during power-up, brown-out, or input disconnection - preventing unintended activation of downstream devices like gate drivers or relays. In motor control applications, this fail-safe state avoids shoot-through conditions and aligns with ISO 26262 ASIL-B requirements for controlled shutdown behavior.
Can ADuM3210TRZ-RL7 operate reliably at 125°C ambient temperature?
Yes, ADuM3210TRZ-RL7 is explicitly qualified for continuous operation from −40°C to +125°C ambient, with full electrical specifications guaranteed at 125°C across all supply configurations (3.3 V, 5 V, and mixed). This makes it suitable for under-hood automotive applications, high-power motor drives, and industrial inverters where thermal management is constrained.
