Product details

Overview

ADUM3210TRZ-EP-RL7 from Analog Devices is a dual-channel, unidirectional digital isolator using iCoupler® transformer-based isolation technology, delivering 25 Mbps data rate, 50 ns max propagation delay at 5 V, and reinforced insulation rated to 560 V_PEAK. It operates across −55°C to +125°C with 3.0–5.5 V supplies on both sides and supports voltage translation between 3.3 V and 5 V domains. It is used in isolated SPI interfaces and industrial fieldbus transceivers requiring high ESD robustness.

For engineers reviewing the ADUM3210TRZ-EP-RL7 datasheet, ADUM3210TRZ-EP-RL7 pinout, ADUM3210TRZ-EP-RL7 application, or ADUM3210TRZ-EP-RL7 equivalent, key selection criteria include its military-grade temperature range, 25 kV/µs common-mode transient immunity, default-low output logic behavior, narrow-body SOIC_N-8 package, and compliance with DIN V VDE V 0884-10 (reinforced) and UL 1577 (2500 V_RMS).

Technical Context

The ADUM3210TRZ-EP-RL7 implements two independent unidirectional isolation channels (VIA→VOA, VIB→VOB), each with CMOS-compatible input and output stages coupled via monolithic air-core transformers. Its architecture enables precise timing control with ≤3 ns pulse width distortion and ≤18 ns channel-to-channel skew at 5 V operation.

It features enhanced system-level ESD reliability per IEC 61000-4-x standards and supports mixed-voltage operation (e.g., 5 V side / 3.3 V side), enabling seamless interfacing between legacy and low-voltage subsystems without external level shifters.

Equivalent & Alternatives

The following parts are listed as comparable options for similar digital isolator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM3211TRZ-EP-RL7	1 input on VDD1 side, 1 input on VDD2 side (bidirectional configuration); same package, timing, and isolation specs.	Supports bidirectional data flow (e.g., half-duplex UART), whereas ADUM3210TRZ-EP-RL7 is strictly unidirectional (2 inputs → 2 outputs).	Select ADUM3211TRZ-EP-RL7 when cross-isolation communication (e.g., request/response) is needed; ADUM3210TRZ-EP-RL7 is optimal for master→slave control only.
SI8620ED-B-IS	Capacitive isolation; 25 Mbps; 5000 V_RMS rating; 2.5–5.5 V supply; different pinout (SOIC-8 but non-compatible mapping).	Higher isolation voltage but lacks AQEC qualification and military temperature support; no default-low fail-safe behavior.	Choose SI8620ED-B-IS for cost-sensitive commercial designs where 125°C operation and defense-grade reliability are not required.

Compared with ADUM3210TRZ-EP-RL7, ADUM3211TRZ-EP-RL7 offers bidirectional flexibility at identical performance, while SI8620ED-B-IS trades military qualification and fail-safe defaults for higher isolation voltage and broader supply range - making ADUM3210TRZ-EP-RL7 uniquely suited for safety-critical, extended-temperature embedded systems.

FAQ

What is the default output state of the ADUM3210TRZ-EP-RL7 during power loss?

The ADUM3210TRZ-EP-RL7 has a default-low output characteristic: when either VDD1 or VDD2 is unpowered or below valid operating voltage, both VOA and VOB drive low. This fail-safe behavior prevents unintended activation of downstream circuits such as gate drivers or relay controllers, and is confirmed in the truth tables and general description of the ADUM3210TRZ-EP-RL7 datasheet.

Does the ADUM3210TRZ-EP-RL7 support mixed-voltage operation between 3.3 V and 5 V domains?

Yes, the ADUM3210TRZ-EP-RL7 supports independent 3.0–5.5 V supplies on both sides - enabling true mixed-voltage operation (e.g., 5 V MCU side / 3.3 V sensor side). Electrical characteristics for 5 V/3.3 V and 3.3 V/5 V configurations are fully specified in Tables 7–12 of the ADUM3210TRZ-EP-RL7 datasheet, including propagation delay, current consumption, and logic thresholds.

What safety certifications apply to the ADUM3210TRZ-EP-RL7?

The ADUM3210TRZ-EP-RL7 carries pending approvals for UL 1577 (2500 V_RMS, 1 min), CSA Component Acceptance Notice #5A, and VDE V 0884-10 (reinforced, VIORM = 560 V_PEAK). It is certified to DIN V VDE V 0884-10:2006-12 with partial discharge testing at 1050 V_PEAK, and marked with an asterisk (*) indicating VDE compliance. These ratings are explicitly stated in the Regulatory Information and Insulation Characteristics sections of the ADUM3210TRZ-EP-RL7 documentation.

How does the ADUM3210TRZ-EP-RL7 differ from the commercial-grade ADUM3210ARZ?

The ADUM3210TRZ-EP-RL7 is the enhanced product (EP) variant: it adds AQEC qualification for defense/aerospace use, extended −55°C to +125°C operation, controlled manufacturing baseline, enhanced ESD robustness per IEC 61000-4-x, and full traceability. The commercial ADUM3210ARZ is rated only from −40°C to +105°C and lacks EP-specific reliability and regulatory documentation - differences confirmed in the Enhanced Features and Ordering Guide of the ADUM3210TRZ-EP-RL7 datasheet.

What is the maximum common-mode transient immunity (CMTI) specification for the ADUM3210TRZ-EP-RL7?

The ADUM3210TRZ-EP-RL7 guarantees >25 kV/µs common-mode transient immunity, with typical performance up to 35 kV/µs, tested per IEC 61000-4-4/5 with 1000 V common-mode voltage and 800 V transient magnitude. This value is consistent across all supply configurations (5 V, 3.3 V, and mixed) and is documented in Tables 3, 6, 9, and 12 of the ADUM3210TRZ-EP-RL7 datasheet under AC specifications.
