Product details
Overview
ADUM2201WARWZ from Analog Devices is a dual-channel, reinforced digital isolator based on iCoupler® transformer technology, providing 5 kV rms isolation, dc–10 Mbps data rate, and precise timing (≤3 ns pulse width distortion). It operates across 3.0–5.5 V supplies on both sides, supports 3.3 V/5 V level translation, and is qualified for automotive applications up to 125°C.
For engineers reviewing the ADUM2201WARWZ datasheet, ADUM2201WARWZ pinout, ADUM2201WARWZ application, or ADUM2201WARWZ equivalent, this device delivers high common-mode transient immunity (>25 kV/µs), low power consumption (1.4 mA/channel at 1 Mbps, 3.3 V), and certified reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17) and UL 1577 - critical for medical, industrial, and EV battery monitoring designs.
Technical Context
The ADUM2201WARWZ implements two independent unidirectional isolation channels using monolithic air-core transformers, eliminating LED/photodiode aging and CTR drift inherent in optocouplers. Its patented refresh circuit ensures DC correctness during idle periods and power transitions.
It features codirectional channel matching ≤3 ns and opposing-directional skew ≤22 ns (B grade), with propagation delay ≤55 ns under mixed-voltage operation (3.3 V/5 V). The device supports reinforced insulation with VIORM = 645 V peak and meets IEC 62368-1, IEC 60601-1, and IEC 61010-1 safety standards in the RW-16 wide-body SOIC package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5000 V rms (1 min), certified per UL 1577 and DIN EN IEC 60747-17 - enables safe separation of high-voltage and low-voltage domains in medical and industrial systems. |
| Data Rate | DC to 10 Mbps (NRZ) - supports high-speed serial interfaces including isolated RS-485 and CAN FD physical layer signaling. |
| Pulse Width Distortion | ≤3 ns maximum - preserves signal integrity in timing-critical applications such as motor control PWM feedback loops. |
| Common-Mode Transient Immunity | >25 kV/µs - maintains reliable operation in noisy environments like inverters, battery monitors, and motor drives. |
| Supply Range | 3.0 V to 5.5 V on both sides - enables flexible voltage translation (e.g., 3.3 V MCU ↔ 5 V sensor or transceiver). |
| Operating Temperature | −40°C to +125°C (WB grade) - qualified for under-hood automotive and industrial embedded use. |
| Power Consumption | 1.4 mA/channel max at 1 Mbps (3.3 V) - reduces thermal load and extends battery life in portable and isolated power supply controllers. |
Pinout & Package
ADUM2201WARWZ uses a 16-lead SOIC wide-body (RW-16) package with 7.8 mm creepage and clearance, optimized for reinforced insulation in high-voltage applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 | GND1 | Input-side ground reference; internally shorted - must be connected to a low-impedance local ground plane for noise immunity. |
| 3 | VDD1 | Input-side supply (3.0–5.5 V); requires 0.01–0.1 µF bypass capacitor close to Pin 1/3 to suppress switching noise. |
| 4 | VOA | Output A - isolated logic output driven from input side; compatible with CMOS loads up to 3.2 mA sink/source. |
| 5 | VIB | Input B - logic input referenced to GND1; threshold defined by 0.3×VDD1 / 0.7×VDD1 for robust noise margin. |
| 9, 16 | GND2 | Output-side ground reference; internally shorted - electrically isolated from GND1; forms separate return path for isolated domain. |
| 12 | VOB | Output B - second isolated output; matches VOA timing (≤3 ns PWD) for synchronized signal transfer. |
| 13 | VIA | Input A - logic input referenced to GND1; complements VIB for dual-channel bidirectional isolation when paired with external direction control. |
| 14 | VDD2 | Output-side supply (3.0–5.5 V); bypassing between Pin 14 and Pin 16 is mandatory for stable output drive. |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Eliminates optocoupler wear-out mechanisms (LED degradation, CTR drift) and enables >50-year insulation lifetime under rated conditions. |
| DC-correct refresh circuit | Maintains valid logic state during prolonged static input or power-up/power-down - no external watchdog or refresh logic required. |
| Enhanced ESD robustness | Meets system-level IEC 61000-4-x (ESD, burst, surge) without board-level protection components - reduces BOM count and layout complexity. |
| Reinforced insulation certification | DIN EN IEC 60747-17 (VDE 0884-17) and UL 1577 approval - satisfies 2-MOPP requirements for patient-connected medical equipment (IEC 60601-1). |
| Low-power mixed-voltage operation | Supports 3.3 V/5 V level translation with <2.5 mA/channel at 10 Mbps - enables direct interfacing between low-voltage microcontrollers and higher-voltage peripherals. |

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 kV rms rating; 10 Mbps; 2.5 ns PWD; 2.5 V–5.5 V supply; lower quiescent current (1.1 mA/ch @ 1 Mbps, 3.3 V). | Qualified to AEC-Q100 Grade 1 (−40°C to +125°C); lacks IEC 60601-1 certification - suitable for automotive but not patient-connected medical. | Prefer for cost-sensitive automotive or industrial designs where medical certification is unnecessary and lower static power is prioritized. |
| ISO7721DR | Capacitive isolation; 5000 V rms; 100 Mbps capability; 3 ns PWD; 1.71 V–5.5 V supply; higher speed headroom but larger package (SOIC-8). | UL 1577 and VDE 0884-11 certified; not rated for IEC 60601-1 - limited to industrial/commercial use; no 125°C option. | Choose when future-proofing for >10 Mbps upgrades or when ultra-low supply voltage (1.71 V) operation is required; avoid for medical or extended-temp automotive. |

FAQ
What is the isolation rating and safety certification status of ADUM2201WARWZ?
ADUM2201WARWZ is rated for 5000 V rms isolation (1 minute) and carries UL 1577, DIN EN IEC 60747-17 (VDE 0884-17), IEC 62368-1, IEC 60601-1 (2-MOPP), and IEC 61010-1 certifications. Its VIORM is 645 V peak, supporting reinforced insulation in medical and industrial applications. The RW-16 package provides 7.8 mm creepage and clearance per IEC 60664-1.
Does ADUM2201WARWZ support bidirectional communication on both channels?
No - ADUM2201WARWZ has fixed unidirectional channel assignments: Channel A (Pin 13 → Pin 4) and Channel B (Pin 5 → Pin 12). For bidirectional isolation, external direction-control logic or a different variant (e.g., ADUM2201ARWZ with reversed channel direction) must be used. The ADUM2201WARWZ pinout does not allow software-reconfigurable directionality.
What is the maximum data rate and timing performance of ADUM2201WARWZ?
ADUM2201WARWZ supports dc to 10 Mbps (NRZ) with ≤55 ns propagation delay (mixed 3.3 V/5 V operation), ≤3 ns pulse width distortion, and ≤22 ns opposing-directional channel-to-channel skew (B grade). These values are guaranteed over −40°C to +125°C and enable precise timing in motor control and data acquisition systems.
Can ADUM2201WARWZ operate with different supply voltages on each side?
Yes - ADUM2201WARWZ supports independent 3.0–5.5 V supplies on VDD1 and VDD2, enabling true 3.3 V ↔ 5 V level translation. Electrical characteristics are fully specified for mixed-supply configurations (e.g., 3.3 V input side / 5 V output side), with supply current and timing parameters validated per datasheet Tables 7–12.
How does the refresh feature in ADUM2201WARWZ ensure DC correctness?
The ADUM2201WARWZ incorporates a patented internal refresh circuit that periodically samples and retransmits the last valid logic state across the isolation barrier during static input conditions or power transitions. This prevents output drift or metastability without requiring external clocking or protocol-level keep-alive signals - ensuring deterministic behavior in safety-critical systems.
