Product details
Overview
ADUM2402ARIZ from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation technology, providing bidirectional signal transmission across a reinforced insulation barrier. It supports 3 V/5 V level translation, operates up to 90 Mbps (CRWZ grade), delivers ≤2 ns pulse width distortion and ≤5 ns channel-to-channel matching, and is used in isolated communication interfaces for motor drive gate drivers and medical power supply control loops.
For engineers reviewing the ADUM2402ARIZ datasheet, ADUM2402ARIZ pinout, ADUM2402ARIZ application, or ADUM2402ARIZ equivalent, this page provides verified specifications, SOIC-16 wide-body package details, safety-certified isolation parameters, and validated alternatives for industrial and medical system design.
Technical Context
The ADUM2402ARIZ implements four independent unidirectional channels with two inputs on side 1 (A/B) and two outputs on side 2 (C/D), enabling asymmetric data flow across the isolation barrier. Its monolithic air-core transformer coupling eliminates LED/photodiode aging and current-transfer-ratio drift, supporting stable DC-correct operation via patented refresh circuitry during signal inactivity or power transitions.
It operates with asymmetric supply configurations (e.g., 5 V on VDD1 / 3 V on VDD2), maintains high common-mode transient immunity (>25 kV/µs), and guarantees timing performance including <2 ns pulse width distortion and <5 ns channel-to-channel skew at 90 Mbps - all under full temperature range (–40°C to +105°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5000 V rms for 1 minute (UL 1577); VIORM = 645 V peak (DIN EN IEC 60747-17) |
| Max Data Rate | 90 Mbps (CRWZ grade) - supports high-speed SPI, RS-485, and digital encoder interfaces |
| Pulse Width Distortion | ≤2 ns - ensures minimal duty-cycle error in PWM and clock distribution applications |
| Channel-to-Channel Matching | ≤5 ns - critical for synchronized multi-channel sampling and phase-aligned control signals |
| Supply Voltage Range | 2.7 V to 5.5 V per side - enables mixed-voltage system interfacing (e.g., 3.3 V MCU to 5 V actuator) |
| Common-Mode Transient Immunity | >25 kV/µs - sustains reliable operation in noisy motor drive and industrial power converter environments |
| Operating Temperature | –40°C to +105°C - qualified for under-hood automotive and industrial ambient conditions |
Pinout & Package
ADUM2402ARIZ is housed in a 16-lead SOIC wide-body package (RW-16) with 7.5 mm creepage and clearance, optimized for reinforced insulation in high-voltage systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side power supply | Supplies logic side 1 (inputs A/B); accepts 2.7–5.5 V; decoupling required near pin |
| GND1 | Primary-side ground reference | Return path for side 1 signals; must be separated from GND2 by isolation barrier |
| INA, INB | Digital input channels (side 1) | Accept CMOS-level signals; drive internal transformers; support 0.4 V/1.6 V thresholds at 3 V |
| VDD2 | Secondary-side power supply | Supplies logic side 2 (outputs C/D); independent voltage domain; enables level translation |
| GND2 | Secondary-side ground reference | Return path for side 2 signals; galvanically isolated from GND1 |
| OUTC, OUTD | Digital output channels (side 2) | CMOS-compatible outputs; drive loads up to 3.2 mA; rail-to-rail swing referenced to VDD2 |
| NC | No-connect pins (pins 5, 11, 12, 16) | Internally unused; must remain unconnected per datasheet; no routing or thermal tie recommended |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional channel configuration | Two inputs on side 1 (A/B), two outputs on side 2 (C/D) - enables asymmetric control/data partitioning across isolation barrier |
| Patented refresh circuitry | Maintains DC correctness during static input states and power-up/power-down - eliminates need for external watchdog or refresh logic |
| 3 V/5 V level translation | Supports mixed-supply systems without external level shifters - e.g., 3.3 V microcontroller communicating with 5 V PLC I/O |
| High-temperature operation | Rated for continuous operation up to +105°C - suitable for enclosed motor drives and medical power supplies |
| Low dynamic power consumption | 0.10 mA/Mbps (input) and 0.03 mA/Mbps (output) at 3 V - reduces thermal load in dense PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8642ED-B-IS | Capacitive isolation; 5000 V rms rating; 100 Mbps max; 2.5 ns PWD; 4.5 ns skew; 2.5–5.5 V supply | Higher ESD tolerance (4 kV HBM); lower propagation delay variation over temperature; no refresh circuit needed | Preferred where ultra-low jitter and wide-temp stability outweigh transformer-based noise immunity advantages |

Compared with SI8642ED-B-IS and ISO6742FDWR, ADUM2402ARIZ offers superior common-mode transient immunity (>25 kV/µs) and proven reliability in high-noise motor control, but requires careful layout for transformer coupling and lacks built-in fault reporting.

FAQ
What is the maximum data rate supported by ADUM2402ARIZ?
ADUM2402ARIZ supports up to 90 Mbps in CRWZ-grade operation, verified under load (CL = 15 pF, CMOS levels). This maximum rate is guaranteed with ≤2 ns pulse width distortion and applies across the full operating temperature range (–40°C to +105°C). The device also supports lower-speed modes (1 Mbps and 10 Mbps) with corresponding reductions in supply current and timing variation. ADUM2402ARIZ achieves this performance using iCoupler® transformer isolation without compromising DC correctness.
Does ADUM2402ARIZ support mixed-voltage operation between its two sides?
Yes, ADUM2402ARIZ supports true mixed-voltage operation: VDD1 can be 2.7–5.5 V while VDD2 is independently set to 2.7–5.5 V, enabling 3 V/5 V or 5 V/3 V level translation. Input thresholds adapt automatically (VIH = 1.6 V at 3 V, 2.0 V at 5 V), and output drive strength scales with the local VDD2 rail. This eliminates external level shifters in interfaces such as 3.3 V microcontrollers driving 5 V gate drivers - a core capability confirmed in Tables 2 and 3 of the ADUM2402ARIZ datasheet.
What safety certifications apply to ADUM2402ARIZ?
ADUM2402ARIZ holds UL 1577 (5000 V rms for 1 minute), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (medical), IEC/CSA 61010-1 (test equipment), CQC GB 4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 V peak. These certifications apply to the RW-16 package variant (which ADUM2402ARIZ uses) and validate reinforced insulation for end-equipment compliance in industrial, medical, and energy applications.
How does ADUM2402ARIZ ensure DC correctness during signal inactivity?
ADUM2402ARIZ incorporates a patented internal refresh circuit that periodically samples and retransmits the last valid logic state across the isolation barrier - ensuring correct DC output levels even when input signals remain static for extended periods or during power-up/power-down transitions. This eliminates the need for external refresh clocks or watchdog timers and is intrinsic to iCoupler® architecture, distinguishing ADUM2402ARIZ from optocouplers and many capacitive isolators.
What is the channel configuration of ADUM2402ARIZ?
ADUM2402ARIZ has a fixed 2+2 unidirectional channel configuration: two inputs (INA, INB) on side 1 and two outputs (OUTC, OUTD) on side 2. Unlike ADUM2400 (4-channel uni) or ADUM2401 (3+1), ADUM2402ARIZ is optimized for asymmetric control architectures - for example, sending command signals from a low-voltage controller to high-voltage peripherals while receiving status feedback through separate dedicated channels.
