Product details
Overview
ADUM3301ARWZ-RL from Analog Devices is a triple-channel, bidirectional digital isolator based on iCoupler® transformer technology, delivering 2500 Vrms isolation, 90 Mbps data rate (CRW grade), and 3.3 V/5 V level translation across the barrier. It features output enable control, <2 ns pulse width distortion, and operates from −40°C to +105°C in industrial automation interfaces requiring robust ESD immunity per IEC 61000-4-x.
For engineers reviewing the ADUM3301ARWZ-RL datasheet, ADUM3301ARWZ-RL pinout, ADUM3301ARWZ-RL application, or ADUM3301ARWZ-RL equivalent, this page delivers verified specifications, real-world timing behavior, safety-certified insulation parameters, and validated alternatives for SPI isolation, RS-485 transceiver coupling, and multichannel PLC I/O designs.
Technical Context
The ADUM3301ARWZ-RL implements three independent galvanically isolated signal channels using monolithic air-core transformers, enabling true bidirectional communication without external direction control logic. Its patented refresh circuit ensures DC correctness during idle periods and power transitions, eliminating optocoupler-like data loss at zero frequency.
It supports mixed-voltage operation (3.3 V/5 V or 5 V/3.3 V) with input thresholds adaptive to supply voltage (VIH = 1.6 V @ 3.3 V, 2.0 V @ 5 V), and achieves >25 kV/µs common-mode transient immunity via differential transformer coupling and internal noise rejection architecture.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 2500 Vrms for 1 minute (UL 1577); VIORM = 560 Vpeak (DIN EN IEC 60747-17) |
| Max Data Rate | 90 Mbps NRZ - enables high-speed SPI clock domains and fast serial bus isolation |
| Pulse Width Distortion | ≤2 ns - preserves signal integrity in timing-critical applications like encoder feedback |
| Channel-to-Channel Matching | ≤5 ns (codirectional), ≤6 ns (opposing-directional) - critical for synchronized multi-signal acquisition |
| Supply Voltage Range | 3.0–3.6 V or 4.5–5.5 V per side - supports mixed-voltage system-level interfacing |
| Quiescent Current | ≤3.1 mA (VDD1) + ≤2.3 mA (VDD2) at 3.3 V - enables low-power isolated sensor nodes |
| Operating Temperature | −40°C to +105°C - qualified for industrial motor drives and factory automation environments |
Pinout & Package
ADUM3301ARWZ-RL is housed in a 16-lead SOIC wide-body (7.5 mm body width), RoHS-compliant package with creepage/clearance ≥8.0 mm, optimized for reinforced insulation in industrial equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side power supply | Supplies input-side logic and isolation transmitter; accepts 3.0–5.5 V |
| GND1 | Primary-side ground reference | Reference for all input signals and VDD1; must be separated from GND2 by isolation barrier |
| INA, INB, INC | Input signal terminals (side 1) | Accept CMOS-level logic; support 3.3 V/5 V thresholds depending on VDD1 |
| VDD2 | Secondary-side power supply | Supplies output-side logic and isolation receiver; independent voltage domain from VDD1 |
| GND2 | Secondary-side ground reference | Reference for all output signals and VDD2; galvanically isolated from GND1 |
| OUTA, OUTB, OUTC | Output signal terminals (side 2) | Drive CMOS loads up to 3.2 mA; logic levels referenced to VDD2 |
| EN | Output enable control | Active-low; places all outputs in high-impedance state when asserted - enables bus sharing |
Key Features

Applications
| SPI Interface Isolation | RS-485 Transceiver Isolation |
|---|---|
Use Scenario: Isolating SPI clock, MOSI, MISO, and CS lines between MCU and isolated ADC/DAC in programmable logic controllers. IC Role / Device Role / Timing Role: Provides galvanic separation of control and data paths while preserving sub-10 ns timing alignment across all three channels. Use Value: Enables safe, noise-immune communication in 24 V industrial backplanes where ground loops and transients exceed 1 kV. |
Use Scenario: Coupling UART signals to RS-485 transceivers in distributed I/O modules exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Isolates driver enable, DE/RE control, and differential data pair (A/B) with matched propagation delay to prevent bus contention. Use Value: Meets IEC 61000-4-5 surge immunity requirements without adding discrete TVS or RC snubbers on the controller side. |
| Industrial Fieldbus Node | Motor Drive Control Interface |

Use Scenario: Isolating PWM gate drive enable, fault feedback, and current sense signals in servo amplifier designs. IC Role / Device Role / Timing Role: Delivers synchronized enable/disable of three half-bridge drivers with <2 ns pulse width distortion to prevent shoot-through. Use Value: Reduces risk of IGBT short-circuit failure by ensuring precise timing alignment under fast dv/dt transients (>25 kV/µs). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM3301BRWZ-RL | 10 Mbps max data rate; 3 ns PWD; lower quiescent current (2.0 mA VDD1 @ 3.3 V) | Better suited for cost-sensitive 10 Mbps SPI or UART isolation where 90 Mbps headroom is unnecessary | Select when system bandwidth is ≤10 Mbps and lowest possible static power is prioritized |
| SI8631BB-B-IS | Capacitive isolation; 100 Mbps rating; 5 kVrms isolation; different pinout (SOIC-16 narrow) | Requires layout revision due to non-pin-compatible footprint and different EN pin assignment | Consider only if higher isolation voltage (5 kV) and capacitive noise rejection are required, and board redesign is acceptable |
Compared with ADUM3301ARWZ-RL, the ADUM3301BRWZ-RL trades speed for lower power and cost in mid-speed applications, while SI8631BB-B-IS offers higher isolation voltage but demands PCB rework and lacks the same ESD system-level validation profile.

FAQ
What is the maximum guaranteed data rate for ADUM3301ARWZ-RL?
The ADUM3301ARWZ-RL is rated for a maximum guaranteed data rate of 90 Mbps (NRZ) with pulse width distortion ≤2 ns. This specification is validated under load conditions (CL = 15 pF, CMOS levels) and applies across the full operating temperature range (−40°C to +105°C). The CRW grade designation confirms this performance tier, distinguishing it from the 1 Mbps (ARWZ) and 10 Mbps (BRWZ) variants in the same family.
Does ADUM3301ARWZ-RL support level translation between 3.3 V and 5 V domains?
Yes, ADUM3301ARWZ-RL natively supports bidirectional level translation: inputs on the VDD1 side accept logic thresholds compatible with either 3.3 V (VIH = 1.6 V) or 5 V (VIH = 2.0 V) supplies, while outputs on the VDD2 side drive logic levels referenced to their local supply. This allows direct interface between a 3.3 V microcontroller and a 5 V peripheral - or vice versa - without external level-shifting components.
What safety certifications apply to ADUM3301ARWZ-RL?
ADUM3301ARWZ-RL carries UL 1577 (2500 Vrms/1 min), DIN EN IEC 60747-17 (VDE 0884-17, VIORM = 560 Vpeak), IEC/EN/CSA 62368-1, IEC/CSA 60601-1, and IEC/CSA 61010-1 certifications. These cover reinforced insulation for industrial, medical, and measurement equipment, with test evidence supporting system-level ESD robustness per IEC 61000-4-2.
How does the refresh feature in ADUM3301ARWZ-RL improve system reliability?
The refresh feature in ADUM3301ARWZ-RL continuously monitors static input states and injects periodic pulses to maintain correct output logic levels during prolonged DC conditions or power transitions. This prevents output latch-up or metastability that can occur in transformer-based isolators during idle periods - ensuring deterministic behavior in safety-critical PLC I/O and motor enable circuits.
Is ADUM3301ARWZ-RL pin-compatible with other ADuM330x variants?
Yes, ADUM3301ARWZ-RL shares identical pinout, package (16-lead SOIC wide), and footprint with all ADuM3300/ADuM3301 variants (e.g., ADUM3301BRWZ-RL, ADUM3301CRWZ-RL). This allows drop-in replacement within the same grade family - though data rate, power consumption, and timing specs differ, requiring firmware or layout verification only when crossing speed grades.
