Product details
Overview
ADUM2201BRIZ from Analog Devices is a dual-channel digital isolator using iCoupler® transformer-based isolation, providing 5 kVrms reinforced insulation, 10 Mbps data rate (NRZ), and precise timing with ≤3 ns pulse width distortion and ≤3 ns channel-to-channel matching. It operates across 3.0–5.5 V on both sides, enabling 3.3 V/5 V level translation in industrial motor drives and medical equipment interfaces.
For engineers reviewing the ADUM2201BRIZ datasheet, ADUM2201BRIZ pinout, ADUM2201BRIZ application, or ADUM2201BRIZ equivalent, key selection factors include its B-grade timing performance, 16-lead SOIC wide-body (RI-16-2) package with 8.7 mm creepage, reinforced insulation per VDE 0884-17 (VIORM = 645 Vpeak), and automotive-qualified operation up to +125°C.
Technical Context
The ADUM2201BRIZ implements two independent unidirectional isolation channels using monolithic air-core transformers and high-speed CMOS circuitry-eliminating LED/photodiode aging and CTR drift inherent in optocouplers. Its patented refresh circuit ensures DC correctness during idle periods and power transitions.
It supports mixed-voltage operation (e.g., 5 V side 1 / 3.3 V side 2), delivers >25 kV/µs common-mode transient immunity, and meets reinforced insulation requirements for IEC 60601-1 (2 MOPP), IEC 61010-1, and IEC 62368-1 across both RI-16-2 and RW-16 packages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5000 Vrms for 1 minute - certified reinforced insulation barrier per UL 1577 and VDE 0884-17. |
| Data Rate | DC to 10 Mbps (NRZ) - supports high-speed serial interfaces like RS-485 and SPI without timing degradation. |
| Pulse Width Distortion | ≤3 ns maximum - ensures minimal duty-cycle error in PWM or clock forwarding applications. |
| Channel Matching | ≤3 ns codirectional skew - critical for synchronized signal routing in motor control gate drivers. |
| Supply Range | 3.0 V to 5.5 V on both sides - enables bidirectional level translation between 3.3 V microcontrollers and 5 V peripherals. |
| Common-Mode Immunity | >25 kV/µs - maintains signal integrity in noisy environments such as inverters and battery monitoring systems. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial power electronics. |
Pinout & Package
ADUM2201BRIZ uses the 16-lead SOIC wide-body enhanced creepage package (RI-16-2), with 8.7 mm minimum creepage and clearance, optimized for reinforced insulation in medical and industrial safety-critical designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 | GND1 | Input-side ground reference; internally shorted - requires low-inductance connection to side-1 PCB ground plane. |
| 2, 6, 8, 10, 11, 15 | NC | No internal connection - must remain unconnected per datasheet; no routing or copper fill allowed. |
| 3 | VDD1 | Input-side supply (3.0–5.5 V); bypass with 0.01–0.1 µF capacitor within 2 mm trace length. |
| 4 | VOA | Output of Channel A - drives downstream logic on isolated side; 3.2 mA sink capability at 3.3 V. |
| 5 | VIB | Input to Channel B - accepts CMOS-level signals from non-isolated controller; VIH = 0.7×VDD1. |
| 9, 16 | GND2 | Output-side ground reference; internally shorted - forms return path for isolated logic outputs. |
| 12 | VOB | Output of Channel B - complements VOA for dual-signal isolation (e.g., UART TX/RX or PWM pairs). |
| 13 | VIA | Input to Channel A - receives primary control signal; matches VIB electrical thresholds and timing. |
| 14 | VDD2 | Output-side supply (3.0–5.5 V); independent of VDD1 - enables true galvanic level shifting. |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Eliminates optocoupler wear-out mechanisms and guarantees stable propagation delay over lifetime and temperature. |
| Patented refresh circuit | Maintains DC logic state during signal inactivity or power-up - essential for fail-safe system initialization. |
| VDE 0884-17 reinforced insulation | VIORM = 645 Vpeak with 1209 Vpeak production test - meets 2 MOPP requirements for IEC 60601-1 medical devices. |
| Low dynamic current | 0.19 mA/Mbps input + 0.05 mA/Mbps output - reduces thermal load in compact, sealed enclosures. |
| ESD-hardened design | Enhanced system-level robustness per IEC 61000-4-x - minimizes layout-dependent susceptibility to ESD bursts. |

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 |
|---|---|---|---|
| ADUM2201ARIZ | A-grade timing: 40 ns max PWD vs. B-grade's 3 ns; higher propagation delay skew (15 ns vs. 3 ns). | Suitable for lower-speed industrial controls where <10 Mbps is sufficient and cost sensitivity outweighs precision timing. | Select ADUM2201ARIZ only if system-level jitter budget allows ≥40 ns PWD and channel skew tolerance exceeds 10 ns. |
| SI8621ED-B-IS | Capacitive isolation; 5 kVrms, 10 Mbps, but VIORM = 500 Vpeak (vs. 645 Vpeak), no VDE 0884-17 certification. | Lacks reinforced insulation rating for IEC 60601-1 medical use; limited to industrial/commercial safety classes. | Choose SI8621ED-B-IS only when medical or high-reliability industrial certifications are not required and capacitive architecture is preferred. |
Compared with ADUM2201ARIZ and SI8621ED-B-IS, the ADUM2201BRIZ uniquely combines B-grade precision timing, VDE 0884-17 reinforced insulation, and automotive qualification - making it the sole option for safety-critical, high-speed, and high-temperature applications demanding guaranteed 3 ns PWD and 645 Vpeak working voltage.

FAQ
What is the isolation rating and safety certification of ADUM2201BRIZ?
ADUM2201BRIZ provides 5000 Vrms isolation for 1 minute per UL 1577 and is certified to DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 Vpeak. It holds reinforced insulation ratings for IEC 60601-1 (2 MOPP), IEC 61010-1, and IEC 62368-1, validated in the RI-16-2 package with 8.7 mm creepage. These certifications are explicitly confirmed for ADUM2201BRIZ in the official Rev. H datasheet.
How does ADUM2201BRIZ differ from ADUM2201ARIZ?
ADUM2201BRIZ is the B-grade variant with tighter timing specifications: ≤3 ns pulse width distortion and ≤3 ns codirectional channel matching, versus ≤40 ns PWD and ≤15 ns skew for ADUM2201ARIZ. Both share identical pinout, package, and isolation ratings, but ADUM2201BRIZ is specified for high-speed, low-jitter applications such as motor control PWM synchronization where timing precision is critical.
Can ADUM2201BRIZ operate with different supply voltages on each side?
Yes, ADUM2201BRIZ supports mixed-supply operation: VDD1 and VDD2 can independently range from 3.0 V to 5.5 V, enabling true 3.3 V ↔ 5 V level translation across the isolation barrier. This is verified in Tables 7–10 of the datasheet for configurations including 5 V/3.3 V and 3.3 V/5 V, with full timing and current specifications maintained.
What is the maximum data rate and corresponding power consumption of ADUM2201BRIZ?
ADUM2201BRIZ supports up to 10 Mbps (NRZ) with typical supply current of 1.6 mA per channel at 1 Mbps (3.3 V) and 2.5 mA per channel at 10 Mbps (3.3 V). At 5 V, it draws 1.1 mA/channel at 1 Mbps and 4.2 mA/channel at 10 Mbps - values confirmed in Tables 2 and 5 of the Rev. H datasheet for the B-grade device.
Does ADUM2201BRIZ require external components for basic operation?
No, ADUM2201BRIZ requires no external drivers, resistors, or level shifters. Only 0.01–0.1 µF bypass capacitors are recommended between VDD1–GND1 (Pins 3–1/7) and VDD2–GND2 (Pins 14–9/16), placed within 2 mm trace length. All logic interfaces are CMOS-compatible with standard VIH/VIL thresholds - confirmed in Tables 3, 6, 9, and 12.
