Product details
Overview
ADuM3210BRZ 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 across −40°C to +125°C and delivers precise timing with ≤3 ns pulse width distortion and ≤3 ns channel-to-channel matching-ideal for SPI isolation in motor drive control systems.
For engineers reviewing the ADuM3210BRZ datasheet, ADuM3210BRZ pinout, ADuM3210BRZ application, or ADuM3210BRZ equivalent, key selection criteria include its 125°C automotive-grade qualification, high common-mode transient immunity (>25 kV/µs), dual-supply voltage flexibility (3.3 V/5 V), and enhanced system-level ESD reliability per IEC 61000-4-x.
Technical Context
The ADuM3210BRZ implements two independent unidirectional isolation channels using monolithic air-core transformers, eliminating LED-photodiode aging and CTR drift inherent in optocouplers. Its architecture supports mixed-voltage operation (e.g., 3.3 V input side / 5 V output side) and maintains DC correctness without refresh circuitry.
It features a default-low output state, distinguishing it from the ADuM3200/ADuM3201 series. The device meets DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation (VIORM = 560 VPEAK) and carries UL 1577, IEC/EN/CSA 62368-1, and IEC/CSA 61010-1 safety certifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 25 Mbps (NRZ); enables high-speed SPI, RS-485, and digital field bus isolation without signal degradation. |
| Pulse Width Distortion | ≤3 ns max (at 5 V); ensures minimal duty-cycle error in clock or PWM signal transmission across isolation barrier. |
| Channel-to-Channel Matching | ≤3 ns max (codirectional); critical for synchronized dual-signal paths such as complementary gate drive or differential data pairs. |
| Common-Mode Transient Immunity | >25 kV/µs; sustains reliable operation in noisy industrial/motor drive environments with fast-switching power stages. |
| Supply Voltage Range | 3.0–3.6 V or 4.5–5.5 V per side; supports mixed-voltage interfaces (e.g., 3.3 V MCU to 5 V peripheral) without external level shifters. |
| Operating Temperature | −40°C to +125°C; qualified for under-hood automotive applications including battery monitors and hybrid electric vehicle inverters. |
| Isolation Rating | 2500 VRMS for 1 minute (UL 1577); reinforced insulation per VDE 0884-17 (VIORM = 560 VPEAK) enables safe separation in mains-connected systems. |
Pinout & Package
Narrow-body, RoHS-compliant 8-lead SOIC package (SOIC_N-8), 5.3 mm × 6.2 mm footprint, 1.75 mm height. Creepage and clearance ≥4.0 mm per safety standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (VDD1) | Primary-side supply | Power input for Channel A input side; accepts 3.3 V or 5 V; decoupling capacitor required. |
| Pin 2 (GND1) | Primary-side ground | Reference for Channel A input signals and VDD1; must be isolated from secondary ground. |

Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Eliminates optocoupler LED aging and CTR variation; enables stable 50-year lifetime and predictable propagation delay over temperature. |
| Enhanced system-level ESD | Robustness per IEC 61000-4-2/4-4/4-5 exceeds legacy isolators; reduces board-level ESD protection component count. |

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 |
|---|---|---|---|
| Si8620ED-B-IS | Capacitive isolation; 25 Mbps; 3.3 V only; no mixed-voltage support; lower CMTI (20 kV/µs). | Limited to single-supply systems; lacks 5 V compatibility and automotive temp range. | Prefer when cost-sensitive, single-rail designs dominate and 125°C operation is not required. |
| ISO7721D | Capacitive isolation; 100 Mbps; 3.3/5 V; default-high output; higher quiescent current (1.8 mA/ch @ 0 Mbps). | Higher speed but incompatible default state; requires external pull-down for safety-critical low-default behavior. | Select only if 100 Mbps is mandatory and system can accommodate active-high fault response. |
Compared with Si8620ED-B-IS and ISO7721D, the ADuM3210BRZ uniquely combines default-low safety state, 125°C automotive qualification, mixed-voltage level translation, and VDE-reinforced insulation-making it optimal for high-reliability motor control and EV battery management where fail-safe behavior and thermal robustness are non-negotiable.

FAQ
What is the maximum data rate supported by the ADuM3210BRZ?
The ADuM3210BRZ supports a maximum data rate of 25 Mbps in NRZ format. This is validated across all operating conditions-including 3.3 V/5 V mixed-supply configurations and at full temperature range (−40°C to +125°C). At 10 Mbps, typical pulse width distortion remains ≤3 ns, ensuring signal integrity for high-speed SPI and digital field bus protocols.
Does the ADuM3210BRZ support level translation between 3.3 V and 5 V domains?
Yes, the ADuM3210BRZ fully supports bidirectional level translation: VDD1 may be 3.3 V while VDD2 is 5 V, or vice versa. Input thresholds scale to respective VDDx (VIH = 0.7×VDDx), and output drive strength is specified for both supply combinations-enabling direct interfacing between low-voltage MCUs and higher-voltage peripherals without external translators.
What safety certifications does the ADuM3210BRZ hold?
The ADuM3210BRZ is certified to UL 1577 (2500 VRMS, 1 min), DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation (VIORM = 560 VPEAK), IEC/EN/CSA 62368-1, and IEC/CSA 61010-1. These approvals validate its use in medical, industrial, and automotive equipment requiring basic or reinforced isolation barriers.
How does the ADuM3210BRZ differ from the ADuM3200 series?
The ADuM3210BRZ has a default-low output state, whereas the ADuM3200/ADuM3201 series feature default-high outputs. This makes ADuM3210BRZ preferable in safety-critical applications like gate drive enable/disable, where a powered-off or faulted state must assert logic low. Both share iCoupler technology and similar speed/power specs.
Is the ADuM3210BRZ suitable for automotive applications?
Yes-the ADuM3210BRZ is explicitly qualified for automotive use: it meets AEC-Q100 Grade 1 (−40°C to +125°C), carries VDE 0884-17 reinforced insulation certification, and is referenced in Analog Devices' Automotive Products section for hybrid electric vehicle battery monitors and motor drives.
