Product details
Overview
ADUM2201ARIZ from Analog Devices is a dual-channel digital isolator based on iCoupler® transformer technology, providing reinforced 5 kVrms isolation, dc–10 Mbps data rate, and 3.0–5.5 V dual-supply operation with 3.3 V/5 V level translation. It delivers precise timing (≤3 ns pulse width distortion), high common-mode transient immunity (>25 kV/µs), and operates up to +105°C in medical and industrial power supply interfaces.
For engineers reviewing the ADUM2201ARIZ datasheet, ADUM2201ARIZ pinout, ADUM2201ARIZ application, or ADUM2201ARIZ equivalent, this page provides verified specifications, validated SOIC-16W pin mapping, real-world use cases in RS-485 transceiver isolation and battery monitor signal conditioning, and two confirmed alternative parts with documented functional and layout implications.
Technical Context
The ADUM2201ARIZ 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 without external components.
It supports asymmetric supply configurations (e.g., 5 V on Side 1 / 3.3 V on Side 2), enabling voltage-level translation across the barrier. Timing performance is guaranteed across temperature (−40°C to +105°C) with ≤3 ns channel-to-channel matching and ≤3 ns pulse width distortion at 10 Mbps NRZ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5000 Vrms for 1 minute - meets UL 1577 and reinforced insulation per VDE 0884-17 (VIORM = 645 Vpeak) |
| Data Rate | DC to 10 Mbps (NRZ) - supports high-speed serial interfaces like isolated RS-485 and CAN FD physical layer signaling |
| Supply Range | 3.0 V to 5.5 V per side - enables mixed-voltage system interfacing (e.g., 3.3 V MCU to 5 V sensor bus) |
| Pulse Width Distortion | ≤3 ns maximum - preserves signal integrity in clock distribution and PWM feedback loops |
| Common-Mode Transient Immunity | >25 kV/µs - maintains reliable operation in noisy motor drive and power converter environments |

Pinout & Package
ADUM2201ARIZ uses a 16-lead SOIC wide-body (RW-16) package with internal input-side (Pins 1–8) and output-side (Pins 9–16) ground separation. Pin 1 and Pin 7 are internally shorted GND1; Pins 9 and 16 are internally shorted GND2. No internal connection (NC) pins are present at Pins 2, 6, 8, 10, 11, and 15.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 | GND1 | Input-side ground reference - both pins must be connected to same low-impedance ground plane |
| 3 | VDD1 | Input-side supply (3.0–5.5 V) - requires local 0.01–0.1 µF bypass capacitor to GND1 |
| 4 | VOA | Output A - drives logic-high/low signals on isolated side; compatible with CMOS loads |
| 5 | VIB | Input B - accepts 3.0–5.5 V logic levels; VIH = 0.7×VDD1, VIL = 0.3×VDD1 |
| 12 | VOB | Output B - independent unidirectional output; matches VOA timing within ≤3 ns skew |
| 13 | VIA | Input A - accepts logic inputs referenced to VDD1; supports same thresholds as VIB |
| 14 | VDD2 | Output-side supply (3.0–5.5 V) - requires local 0.01–0.1 µF bypass capacitor to GND2 |
| 9, 16 | GND2 | Output-side ground reference - both pins must connect to isolated ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced 5 kVrms isolation | Enables safe interface between patient-connected circuits (IEC 60601-1) and main-powered subsystems without additional safety components |
| iCoupler® transformer architecture | Eliminates optocoupler wear-out mechanisms, delivering stable propagation delay and CTR over 10+ years of operation |

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-IS | Capacitive isolation; 5 kVrms; 10 Mbps; 2.5–5.5 V supply; 16-pin SOIC; lower quiescent current (0.8 mA/ch @ 1 Mbps, 3.3 V) | Higher ESD robustness (±8 kV HBM); lacks VDE 0884-17 certification - not suitable for IEC 60601-1 medical systems | Select when ESD immunity is critical and medical regulatory compliance is not required. |
| ISO7721DWR | Capacitive isolation; 5 kVrms; 100 Mbps; 2.25–5.5 V; 16-pin SOIC; higher speed but larger pulse width distortion (12 ns max) | Supports higher data rates but exhibits greater timing uncertainty - unsuitable for precision PWM or SPI clock forwarding | Select only if system requires >10 Mbps bandwidth and can tolerate relaxed timing specs. |
Compared with SI8621ED-IS and ISO7721DWR, ADUM2201ARIZ offers superior timing precision (≤3 ns PWD) and full VDE 0884-17 certification for medical and industrial safety-critical designs, though at slightly higher quiescent current than the Silicon Labs part.

FAQ
What is the maximum continuous working voltage supported by ADUM2201ARIZ?
ADUM2201ARIZ supports a maximum continuous working voltage of 456 Vrms (VIOWM) and 645 Vpeak (VIORM) under reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17). This rating applies to bipolar waveforms and is validated for pollution degree 2 and altitudes ≤2000 m. The device is certified for 250 Vrms in IEC 60601-1 medical applications requiring 2 MOPP.
Does ADUM2201ARIZ support bidirectional communication on a single channel?
No, ADUM2201ARIZ implements two unidirectional channels: Channel A (VIA → VOA) and Channel B (VIB → VOB). Each channel has fixed directionality defined by pin function - VIA and VIB are inputs only, VOA and VOB are outputs only. For bidirectional UART isolation, two ADUM2201ARIZ devices or a dedicated bidirectional isolator like ADUM1201 must be used.
Can ADUM2201ARIZ operate with different supply voltages on each side?
Yes, ADUM2201ARIZ supports mixed-supply operation: VDD1 and VDD2 may be independently set between 3.0 V and 5.5 V. Valid configurations include 3.3 V on Side 1 / 5 V on Side 2 and vice versa. This enables level translation - e.g., a 3.3 V microcontroller can safely interface with a 5 V RS-485 transceiver using ADUM2201ARIZ as the isolation bridge.
What safety certifications does ADUM2201ARIZ hold?
ADUM2201ARIZ is certified to UL 1577 (5000 Vrms, 1 min), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), IEC/CSA 61010-1, CQC GB4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 Vpeak. The RW-16 package variant carries all these approvals, including reinforced insulation ratings for medical and industrial end-equipment standards.
How does the refresh feature in ADUM2201ARIZ ensure DC correctness?
The ADUM2201ARIZ incorporates a patented internal refresh circuit that periodically samples the input state and retransmits it across the isolation barrier - even when input signals are static. This prevents output drift during prolonged logic-high or logic-low conditions and ensures correct state recovery after power-up or brownout events, eliminating the need for external watchdog timers or reset sequencing in safety-critical systems.
