Product details
Overview
ADUM2400ARWZ from Analog Devices is a quad-channel digital isolator based on iCoupler® transformer technology, providing galvanic isolation between two 2.7–5.5 V domains with bidirectional communication capability. It delivers 1 Mbps maximum data rate, <40 ns pulse width distortion, and 50 ns channel-to-channel matching in a 16-lead SOIC wide-body (RW-16) package, enabling safe signal transmission in motor drive gate driver interfaces.
For engineers reviewing the ADUM2400ARWZ datasheet, ADUM2400ARWZ pinout, ADUM2400ARWZ application, or ADUM2400ARWZ equivalent, this part supports low-speed isolated control signaling in medical power supplies, industrial I/O modules, and PLC backplanes where safety-certified 5000 Vrms isolation and 105°C operation are required.
Technical Context
The ADUM2400ARWZ implements four independent unidirectional isolation channels using monolithic air-core transformers, eliminating LED/photodiode aging and CTR drift inherent in optocouplers. Its architecture includes integrated refresh circuitry to maintain DC correctness during static input conditions and power transitions.
It operates across dual supply domains (VDD1/VDD2), supporting 3 V/5 V level translation and delivering guaranteed timing performance: 50–100 ns propagation delay, ≤40 ns pulse width distortion, and ≥25 kV/µs common-mode transient immunity - all validated under UL 1577 and DIN EN IEC 60747-17 (VDE 0884-17) certification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISO6741QDWR | Capacitive isolation; 1 Mbps rating; 5000 Vrms rating; 16-pin SOIC; lower max temp (105°C same) | Requires external VISO decoupling; no integrated refresh; slightly higher CMTI (35 kV/µs) | Preferred when capacitive architecture is mandated or when sourcing from TI-qualified supply chains |
| Si8641ED-IS | Silicon Labs capacitive isolator; 1 Mbps; 5000 Vrms; 16-pin SOIC; 105°C rating; different pinout | No output enable; no mixed-voltage operation support; higher quiescent current (3.5 mA typical) | Selected for designs already standardized on Si86xx family or requiring AEC-Q100 qualification |
Compared with ISO6741QDWR and Si8641ED-IS, the ADUM2400ARWZ offers native refresh functionality for DC-correctness, seamless 3 V/5 V translation without level shifters, and identical RW-16 footprint compatibility - making it optimal for legacy optocoupler drop-in upgrades in industrial control hardware.

FAQ
What is the maximum data rate supported by the ADUM2400ARWZ?
The ADUM2400ARWZ supports a maximum data rate of 1 Mbps, which is guaranteed to maintain ≤40 ns pulse width distortion under standard test conditions (CL = 15 pF, CMOS levels). This makes ADUM2400ARWZ suitable for isolated enable, fault, and status signaling rather than high-speed serial communication. The 1 Mbps limit reflects its A-grade speed bin within the ADuM2400 family, distinct from the 10 Mbps (B-grade) and 90 Mbps (C-grade) variants.
Does the ADUM2400ARWZ support level translation between 3 V and 5 V domains?
Yes, the ADUM2400ARWZ supports true bidirectional level translation: VDD1 can operate from 2.7 V to 5.5 V independently of VDD2, which also ranges from 2.7 V to 5.5 V. This allows direct interfacing between a 3.3 V microcontroller (VDD1 = 3.3 V) and a 5 V peripheral (VDD2 = 5 V), with logic thresholds automatically adapting (VIH = 2.0 V @ 5 V, 1.6 V @ 3 V). ADUM2400ARWZ requires no external level-shifting components.
What safety certifications apply to the ADUM2400ARWZ?
The ADUM2400ARWZ holds UL 1577 (5000 Vrms for 1 minute), IEC/EN/CSA 62368-1, IEC/CSA 60601-1, IEC/CSA 61010-1, CQC GB 4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) certifications. These cover reinforced insulation for medical, industrial, and measurement equipment. VIORM is rated at 645 Vpeak, and the RW-16 package provides 7.6 mm creepage/clearance - all verified per the ADUM2400ARWZ's specific package variant.
How does the refresh feature in the ADUM2400ARWZ improve system reliability?
The ADUM2400ARWZ incorporates patented refresh circuitry that periodically samples and retransmits the last valid input state during static conditions, ensuring DC-correct output even when input signals remain unchanged for extended periods. This prevents output drift during power-up, power-down, or idle states - a critical advantage over optocouplers and some capacitive isolators that may fail silent in absence of toggling inputs. The refresh rate is 1.2 Mbps (3 V) or 1.1 Mbps (5 V).
Can the ADUM2400ARWZ replace optocouplers in existing designs without PCB changes?
Yes, the ADUM2400ARWZ uses the industry-standard 16-lead SOIC wide-body (RW-16) footprint with identical pad layout and dimensions to common quad optocouplers (e.g., PS2561L-4), enabling direct drop-in replacement. Its logic-compatible inputs/outputs, integrated power supply rejection, and lack of CTR dependency eliminate redesign of biasing networks or timing margins - provided the target application operates within the 1 Mbps data rate and 105°C thermal envelope of ADUM2400ARWZ.
