Product details
Overview
ADUM3300ARWZ from Analog Devices is a triple-channel, unidirectional digital isolator based on iCoupler® transformer technology, designed for galvanic isolation between microcontroller peripherals and industrial I/O or communication interfaces. It supports 3.3 V or 5 V operation on either side, delivers ≤1 Mbps data rate with ≤100 ns propagation delay, and features output enable control and enhanced system-level ESD reliability per IEC 61000-4-x. It is used in isolated SPI data acquisition systems where voltage translation and noise immunity are critical.
For engineers reviewing the ADUM3300ARWZ datasheet, ADUM3300ARWZ pinout, ADUM3300ARWZ application, or ADUM3300ARWZ equivalent, this page provides verified technical context, real-world timing and power specifications, SOIC-16W package details, functional alternatives, and supply-chain support tailored to industrial embedded design and safety-critical isolation requirements.
Technical Context
The ADUM3300ARWZ implements three independent unidirectional isolation channels using monolithic air-core transformers and high-speed CMOS interface circuitry. Its architecture includes a patented refresh feature ensuring DC correctness during idle periods and power transitions, eliminating optocoupler-like drift or latch-up concerns.
All channels operate across a 3.0–5.5 V supply range on both sides, enabling bidirectional level translation (e.g., 3.3 V MCU ↔ 5 V sensor bus). The device guarantees ≤40 ns pulse width distortion and ≤50 ns channel-to-channel matching at its rated 1 Mbps, with common-mode transient immunity exceeding 25 kV/µs - critical for motor drive and PLC backplane environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 3 unidirectional isolation channels - enables isolated SPI clock/MOSI/MISO or discrete control signal routing |
| Max Data Rate | 1 Mbps (NRZ) - sufficient for legacy SPI, RS-485 control, and slow serial sensor interfaces |
| Propagation Delay | 50–100 ns - deterministic latency suitable for closed-loop timing budgets in industrial controllers |
| Pulse Width Distortion | ≤40 ns - preserves duty cycle integrity for PWM or clock forwarding applications |

| Common-Mode Transient Immunity | >25 kV/µs - maintains signal integrity in high-noise motor drives and relay-switched power systems |
| Isolation Rating | 2500 V rms (UL 1577), VIORM = 560 V peak - meets reinforced insulation requirements for IEC 62368-1 and IEC 61010-1 |
| Operating Temperature | −40°C to +105°C - qualified for extended industrial ambient conditions |
Pinout & Package
ADUM3300ARWZ is housed in a 16-lead SOIC wide-body (SOIC_W) RoHS-compliant package with 7.5 mm body width and 1.27 mm pitch. Pinout follows standard ADuM3300 configuration: primary-side inputs (A1–A3), secondary-side outputs (B1–B3), dual supplies (VDD1/VDD2), ground pins (GND1/GND2), and output enable (EN).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2, A3 | Primary-side input signals | Accept logic-level inputs referenced to VDD1/GND1; drive isolated outputs B1–B3 |
| B1, B2, B3 | Secondary-side output signals | Provide CMOS-compatible outputs referenced to VDD2/GND2; support 3.3 V or 5 V logic levels |
| VDD1, GND1 | Primary-side power domain | Supply and reference for input-side circuitry; independent of secondary-side voltage |
| VDD2, GND2 | Secondary-side power domain | Supply and reference for output-side circuitry; enables level translation across isolation barrier |
| EN | Output enable control | Active-low signal that places B1–B3 outputs in high-impedance state - supports bus sharing and power sequencing |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Eliminates LED aging, CTR degradation, and temperature drift inherent in optocouplers - ensures stable performance over 10+ years |

| DC-correct refresh circuit | Maintains output state during static input conditions or power-up/power-down - prevents undefined logic states in safety-critical monitoring paths |
| Low quiescent current | ≤2.4 mA total at VDD1 and ≤1.1 mA at VDD2 (3.3 V/5 V operation, DC–2 Mbps) - extends battery life in isolated sensor nodes |
| High-temperature operation | Rated up to +105°C ambient - supports placement near power stages or in enclosed enclosures without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM3300BRWZ | Higher speed grade: 10 Mbps max data rate, 20–50 ns propagation delay, 3 ns pulse width distortion | Required for faster SPI (≥5 MHz SCLK) or isolated UART at 921.6 kbps; consumes more dynamic current at high rates | Select ADUM3300BRWZ when timing budget demands sub-50 ns channel matching and ≥5 Mbps throughput. |

FAQ
What is the maximum data rate supported by ADUM3300ARWZ?
The ADUM3300ARWZ supports a maximum data rate of 1 Mbps (NRZ) with guaranteed pulse width distortion ≤40 ns. This rating applies across all operating conditions including 3.3 V/3.3 V, 5 V/5 V, and mixed 3.3 V/5 V supply configurations. Higher-speed variants like ADUM3300BRWZ (10 Mbps) and ADUM3300CRWZ (90 Mbps) are available in the same family but require separate ordering.
Does ADUM3300ARWZ support level translation between 3.3 V and 5 V domains?
Yes, ADUM3300ARWZ supports true bidirectional level translation: VDD1 may be 3.3 V while VDD2 is 5 V (or vice versa), with logic thresholds and output drive strengths adapted accordingly. Input high threshold is 2.0 V at 5 V operation and 1.6 V at 3.3 V operation; outputs swing rail-to-rail within their respective supply domains.
What safety certifications does ADUM3300ARWZ hold?
ADUM3300ARWZ is certified to UL 1577 (2500 V rms for 1 minute), DIN EN IEC 60747-17 (VDE 0884-17, VIORM = 560 V peak), IEC/EN/CSA 62368-1, IEC/CSA 60601-1, and IEC/CSA 61010-1. These approvals validate its suitability for reinforced insulation in industrial, medical, and test equipment applications.
How does the refresh feature in ADUM3300ARWZ improve system reliability?
The patented refresh feature in ADUM3300ARWZ continuously monitors input states and retransmits static logic levels across the isolation barrier during idle periods or power transitions. This ensures DC correctness - preventing output glitches or metastability that could occur in competing isolators lacking such circuitry - especially critical in safety-monitoring and watchdog signal paths.
Can ADUM3300ARWZ be used in place of optocouplers in existing designs?
Yes, ADUM3300ARWZ can replace 3-channel optocoupler-based isolation solutions (e.g., HCPL-0738) with direct PCB layout reuse in SOIC-16W footprints. It eliminates current transfer ratio uncertainty, reduces supply current by >90%, removes LED aging concerns, and improves timing consistency - though pin mapping must be verified against the specific optocoupler's channel directionality and enable logic.
