Product details
Overview
ADUM2210SRWZ-RL from Analog Devices is a dual-channel, 5 kV rms reinforced digital isolator using iCoupler® transformer-based technology. It provides bidirectional signal isolation between two independent circuits operating at 3.0–5.5 V per side, supports up to 10 Mbps NRZ data rate, features 3 ns max pulse width distortion and 3 ns max channel-to-channel matching, and is widely deployed in RS-485 transceiver isolation and medical equipment power domains.
For engineers reviewing the ADUM2210SRWZ-RL datasheet, ADUM2210SRWZ-RL pinout, ADUM2210SRWZ-RL application, or ADUM2210SRWZ-RL equivalent, key selection criteria include reinforced 5 kV rms isolation rating, 125°C operation, mixed-voltage level translation (3.3 V/5 V), high common-mode transient immunity (>25 kV/µs), and SOIC-Wide (RW-16) package compatibility with industrial and automotive safety standards.
Technical Context
The ADUM2210SRWZ-RL implements two independent unidirectional isolation channels based on monolithic air-core transformers, eliminating LED/photodiode aging and CTR drift inherent in optocouplers. Its architecture enables precise timing control with <3 ns pulse width distortion and <3 ns channel matching under full temperature range (−40°C to +125°C).
It supports asymmetric supply configurations: VDD1 and VDD2 each operate independently from 3.0 V to 5.5 V, enabling true 3.3 V ↔ 5 V level translation across the barrier. Default-low output logic and integrated refresh circuitry ensure DC correctness without external components, even during extended idle periods.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5000 V rms for 1 minute - meets UL 1577 and reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17) |
| 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 - ensures minimal duty-cycle degradation in clock or PWM transfer applications |
| Channel Matching | ≤3 ns codirectional skew - critical for synchronized dual-signal paths like encoder A/B quadrature or differential bus isolation |
| Common-Mode Transient Immunity | >25 kV/µs - maintains signal integrity in noisy motor drive or power supply gate-drive environments |
| Supply Voltage Range | 3.0 V to 5.5 V per side - enables flexible system-level voltage domain bridging without level shifters |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial power-conversion applications |
Pinout & Package
ADUM2210SRWZ-RL uses a 16-lead SOIC wide-body (RW-16) package with creepage/clearance optimized for reinforced insulation. Pin 1–8 constitute Side 1 (input side); Pins 9–16 constitute Side 2 (output side). Ground pins are separated to maintain isolation integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, GND1 | Side 1 Ground Reference | Return path for input-side logic and supply; must be isolated from GND2 with ≥7.8 mm PCB clearance |
| 3, VDD1 | Side 1 Supply Input | Accepts 3.0–5.5 V; powers input-side logic and transformer driver; requires local 0.1 µF bypass |
| 4, VIA | Input Channel A | Logic-level digital input referenced to VDD1/GND1; compatible with CMOS/TTL thresholds (VIH = 0.7×VDD1) |
| 5, VIB | Input Channel B | Independent logic input on Side 1; supports asynchronous dual-channel isolation |
| 9, 16, GND2 | Side 2 Ground Reference | Return path for output-side logic; galvanically isolated from GND1; defines output logic reference |
| 12, VOB | Output Channel B | Isolated logic output referenced to VDD2/GND2; drives loads up to ±22 mA with VOL ≤ 0.4 V @ 3.2 mA |
| 13, VOA | Output Channel A | Isolated logic output; default-low behavior ensures safe state during power loss or reset |
| 14, VDD2 | Side 2 Supply Input | Accepts 3.0–5.5 V independently of VDD1; enables level translation and dual-domain operation |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Eliminates optocoupler CTR degradation and lifetime uncertainty; enables stable performance over 125°C and >50-year insulation lifetime |
| Reinforced 5 kV rms rating | Meets UL 1577, IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1 - certified for medical and industrial safety-critical systems |
| Mixed-voltage operation | VDD1 and VDD2 independently support 3.3 V and 5 V domains - removes need for external level translators in mixed-supply systems |
| High CMTI (>25 kV/µs) | Prevents data corruption in high-dv/dt environments such as IGBT gate drivers, motor inverters, and SMPS feedback loops |
| Low power at 10 Mbps | 3.7 mA/channel @ 5 V / 10 Mbps or 2.4 mA/channel @ 3.3 V / 10 Mbps - reduces thermal load in dense PCB layouts |

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; 3.75 kV rms rating; 150 Mbps max data rate; different pinout (SOIC-8) | Lacks reinforced 5 kV rating and medical approvals; higher speed but lower isolation margin | Choose when speed >10 Mbps is required and 3.75 kV suffices; verify layout for creepage compliance |
| ISO7721DR | Capacitive isolation; 5000 V rms rating; 100 Mbps max; SOIC-8 package; different pin assignment | Higher speed and lower quiescent current, but not AEC-Q100 qualified and lacks IEC 60601-1 certification | Preferred for cost-sensitive industrial automation where automotive or medical certifications are unnecessary |
Compared with SI8621ED-IS and ISO7721DR, ADUM2210SRWZ-RL delivers certified reinforced 5 kV rms isolation, AEC-Q100 qualification, and explicit IEC 60601-1 2-MOPP compliance - making it uniquely suitable for safety-critical medical and automotive BMS designs where regulatory traceability is mandatory.

FAQ
What is the maximum data rate supported by the ADUM2210SRWZ-RL?
The ADUM2210SRWZ-RL supports a maximum data rate of 10 Mbps in NRZ format across its full operating temperature range (−40°C to +125°C). This is verified in both 3.3 V and 5 V supply configurations, with propagation delay skew maintained at ≤3 ns for timing-critical applications such as encoder interfacing or isolated PWM transmission.
Does the ADUM2210SRWZ-RL support level translation between 3.3 V and 5 V domains?
Yes, the ADUM2210SRWZ-RL supports true bidirectional level translation: VDD1 and VDD2 operate independently from 3.0 V to 5.5 V, allowing one side to run at 3.3 V while the other runs at 5 V. This eliminates external level-shifting components and is explicitly characterized in Tables 7 and 10 of the Rev. G datasheet for mixed-voltage operation.
What safety certifications does the ADUM2210SRWZ-RL hold?
The ADUM2210SRWZ-RL holds UL 1577 (5000 V rms), DIN EN IEC 60747-17 (VDE 0884-17) reinforced insulation (VIORM = 645 V peak), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1 certifications. The RW-16 package variant is explicitly listed in Table 14 for all these approvals.
Is the ADUM2210SRWZ-RL suitable for automotive applications?
Yes - the ADUM2210SRWZ-RL is AEC-Q100 qualified for automotive applications (Grade 1: −40°C to +125°C). It is rated for high-temperature operation and meets stringent ESD and transient immunity requirements per IEC 61000-4-x, making it appropriate for battery monitors, motor control units, and charging systems in hybrid and electric vehicles.
What is the default output state of the ADUM2210SRWZ-RL during power loss?
The ADUM2210SRWZ-RL has a default-low output configuration: when either VDD1 or VDD2 is unpowered, the corresponding outputs (VOA/VOB) transition to logic low within 1 µs of power restoration, as confirmed in Table 20 (Truth Table) of the datasheet. This fail-safe behavior prevents undefined states in safety-critical control paths.
