Product details
Overview
ADuM2211TRWZ from Analog Devices is a dual-channel digital isolator using iCoupler® transformer-based technology, providing reinforced 5 kVrms isolation between two independent signal paths. It operates across 3.0–5.5 V on both sides, supports bidirectional data transfer up to 10 Mbps (NRZ), features default-low outputs, and delivers precise timing with ≤3 ns pulse width distortion and ≤3 ns channel-to-channel matching. It is used in isolated RS-485 transceivers and battery monitor interfaces in hybrid electric vehicles.
For engineers reviewing the ADuM2211TRWZ datasheet, ADuM2211TRWZ pinout, ADuM2211TRWZ application, or ADuM2211TRWZ equivalent, key selection criteria include its 5 kVrms UL 1577 rating, 645 Vpeak VIORM per VDE 0884-17, 125°C operation, mixed-voltage level translation (3.3 V/5 V), and SOIC-Wide (RW-16) package with enhanced creepage clearance.
Technical Context
The ADuM2211TRWZ implements monolithic air-core transformers for galvanic isolation, eliminating LED/photodiode dependencies and enabling stable performance over temperature and lifetime. Its architecture supports independent supply domains (VDD1/VDD2), allowing asymmetric voltage operation-e.g., 5 V on side 1 and 3.3 V on side 2-while maintaining logic compatibility and low propagation delay skew (≤22 ns).
It integrates refresh circuitry to preserve DC correctness during idle periods (refresh period ≤1.8 µs) and achieves >25 kV/µs common-mode transient immunity via differential transformer coupling and layout optimization. The device complies with reinforced insulation requirements per DIN EN IEC 60747-17 (VDE 0884-17) and IEC/EN/CSA 62368-1, with safety-limiting values defined up to 150°C case temperature.

Pinout & Package
ADuM2211TRWZ uses a 16-lead SOIC wide-body (RW-16) package with 7.8 mm minimum creepage and clearance, optimized for reinforced insulation in high-voltage applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, GND1 | Input-side ground reference | Provides return path for VDD1 domain; must be connected to local input ground plane with low-inductance routing. |
| 3, VDD1 | Input-side supply | Accepts 3.0–5.5 V; powers input logic and transformer driver; requires local 0.1 µF bypass capacitor. |
| 4, VOA | Output A (driven) | Logic output from side 1; active-high, default-low; sinks/sourcing capability up to ±18 mA. |
| 5, VIB | Input B (side 1) | CMOS-compatible input referenced to VDD1; VIH = 0.7×VDD1, VIL = 0.3×VDD1. |
| 9, 16, GND2 | Output-side ground reference | Return path for VDD2 domain; galvanically isolated from GND1; critical for noise rejection. |
| 12, VOB | Output B (driven) | Logic output from side 2; matches VOA timing characteristics; shares same drive strength and thresholds. |
| 13, VIA | Input A (side 2) | CMOS input referenced to VDD2; enables bidirectional signal flow across isolation barrier. |
| 14, VDD2 | Output-side supply | Independent 3.0–5.5 V supply; allows level translation; requires dedicated 0.1 µF bypass capacitor. |

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 |
|---|---|---|---|
| SI8621ED-B-IS | Capacitive isolation; 5 kVrms; 10 Mbps; 3.3 V only; 16-pin SOIC wide; VIORM = 600 Vpeak. | Lacks AEC-Q100 qualification; lower VIORM limits use in higher-working-voltage medical or industrial systems. | Prefer when cost-sensitive consumer designs require capacitive isolators and 3.3 V-only operation suffices. |
| ISO7721DR | Capacitive isolation; 5 kVrms; 100 Mbps; 3.3/5 V; 8-pin SOIC; VIORM = 600 Vpeak; default-high outputs. | Higher speed but smaller package limits creepage; default-high behavior requires logic inversion in fail-safe systems. | Select for high-speed industrial comms where board space is constrained and default-high reset behavior aligns with system architecture. |
Compared with SI8621ED-B-IS and ISO7721DR, ADuM2211TRWZ offers superior safety margin (645 Vpeak VIORM), guaranteed AEC-Q100 qualification, and default-low outputs-making it preferred for automotive BMS, medical isolation, and high-reliability industrial power systems where regulatory compliance and deterministic startup behavior are mandatory.

FAQ
What is the isolation rating of ADuM2211TRWZ and which safety standards does it meet?
ADuM2211TRWZ provides 5000 Vrms isolation per UL 1577 for 1 minute and meets reinforced insulation requirements per DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 Vpeak. It is certified to IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1, making ADuM2211TRWZ suitable for medical, industrial, and automotive safety-critical systems.
Does ADuM2211TRWZ support bidirectional communication and mixed supply voltages?
Yes, ADuM2211TRWZ supports true bidirectional signal flow: VIA and VIB serve as inputs on opposite sides, while VOA and VOB are outputs-enabling flexible channel assignment. It operates with independent 3.0–5.5 V supplies on each side, allowing 3.3 V ↔ 5 V level translation without external components, a core capability confirmed in Tables 7–12 of the ADuM2211TRWZ datasheet.
What is the maximum data rate and timing precision of ADuM2211TRWZ?
ADuM2211TRWZ supports DC to 10 Mbps (NRZ) data rates. Its timing precision includes ≤3 ns pulse width distortion and ≤3 ns channel-to-channel matching for codirectional signals, ensuring minimal skew in synchronous applications like isolated clock distribution or PWM control-values verified in Tables 1, 4, 7, and 10 of the official Rev. G datasheet.
How does ADuM2211TRWZ handle power loss or unpowered states on one side?
When VDD1 is unpowered, ADuM2211TRWZ outputs on side 2 (VOA, VOB) default to low within 1 µs after VDD1 restoration, per Table 21. When VDD2 is unpowered, outputs go indeterminate-but VIB remains functional as an input. This behavior is intrinsic to ADuM2211TRWZ's architecture and ensures predictable startup sequencing in fault-tolerant systems.
Is ADuM2211TRWZ qualified for automotive applications?
Yes, ADuM2211TRWZ is AEC-Q100 qualified for automotive Grade 1 (−40°C to +125°C ambient), explicitly stated in the General Description section and Automotive Products section of the datasheet. This qualification covers thermal cycling, humidity, and vibration testing-validating ADuM2211TRWZ for use in battery monitors, motor drives, and charging systems in hybrid and electric vehicles.
