Product details
Overview
ADUM4402BRIZ from Analog Devices is a 5 kVRMS quad-channel digital isolator with bidirectional communication, 3.3 V/5 V level translation, and output enable functionality. It delivers 90 Mbps data rate, <2 ns pulse width distortion, and >25 kV/µs common-mode transient immunity for high-noise industrial motor drive interfaces.
For engineers reviewing the ADUM4402BRIZ datasheet, ADUM4402BRIZ pinout, ADUM4402BRIZ application, or ADUM4402BRIZ equivalent, this page provides verified specifications, safety-certified package details (RI-16), channel-level power consumption at 3.3 V/5 V operation, and real-world design implications of its refresh feature and output enable timing.
Technical Context
The ADUM4402BRIZ implements four independent isolation channels using monolithic air-core transformer technology, enabling simultaneous bidirectional signal transfer across galvanic barriers. Its patented refresh circuit ensures DC correctness during input inactivity and power-up/power-down transitions without external supervision.
It supports mixed-voltage operation (3.3 V/5 V on opposite sides), with guaranteed timing performance up to 90 Mbps NRZ and channel-to-channel matching ≤2 ns. The device meets reinforced insulation requirements per DIN EN IEC 60747-17 (VDE 0884-17) and IEC/CSA 60601-1 (2 MOPP).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 90 Mbps NRZ - supports high-speed serial interfaces like SPI, RS-485 transceiver control, and isolated ADC/DAC links. |
| Isolation Rating | 5000 VRMS for 1 minute - certified for reinforced insulation in medical (IEC 60601-1) and industrial (IEC 62368-1) safety-critical systems. |
| Pulse Width Distortion | ≤2 ns maximum - preserves signal integrity in timing-sensitive applications such as PWM feedback and encoder interfaces. |
| Common-Mode Transient Immunity | >25 kV/µs - maintains reliable operation in high-dV/dt environments like motor drives and switch-mode power supplies. |
| Supply Voltage Range | 3.0 V to 5.5 V per side - enables interoperability between legacy 5 V logic and modern 3.3 V microcontrollers without level shifters. |
| Output Enable Propagation Delay | 6–8 ns - allows fast, deterministic tri-state control of isolated outputs for bus arbitration or fault containment. |
| Quiescent Current per Channel | 0.31 mA (input side, 3.3 V) / 0.27 mA (output side, 3.3 V) - reduces standby power in battery-backed or energy-constrained systems. |
Pinout & Package
ADUM4402BRIZ uses the RI-16 (16-lead SOIC wide body enhanced creepage) package, providing 8.7 mm minimum creepage and clearance for reinforced insulation compliance in high-voltage applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | VDD1, VDD2 | Independent supply inputs for isolated sides - enables asymmetric voltage operation (e.g., 5 V MCU side / 3.3 V sensor side). |
| 2, 8, 9, 15 | GND1, GND2 | Dedicated ground references per side - prevents ground loop coupling and ensures noise-free isolation barrier integrity. |
| 3–6 | VIA–VID | Input-side logic signals - accept CMOS-compatible levels (VIH = 2.0 V @ 5 V, 1.6 V @ 3.3 V) with ±10 µA input leakage. |
| 10 | VE2 | Active-high output enable for Side 2 - disables all VOx outputs (pins 11–14) into high-impedance state within 8 ns. |
| 11–14 | VOD–VOA | Output-side logic signals - drive CMOS loads with VOL ≤ 0.4 V @ 3.2 mA, supporting direct connection to downstream logic. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional channel configuration | Four independent channels with configurable input/output direction per side - eliminates need for separate transmit/receive isolators in full-duplex interfaces. |
| Patented refresh circuit | Maintains DC-correct output states during prolonged input inactivity or power sequencing - removes requirement for external watchdog or clock injection. |
| System-level ESD enhancement | Designed to meet IEC 61000-4-x standards (ESD/burst/surge) - reduces need for external TVS diodes in board-level EMC design. |
| Low-power operation | Consumes ≤20 mA per channel at 90 Mbps (3.3 V) - cuts isolation power by up to 90% versus optocouplers at comparable speeds. |
| Input glitch filter | Rejects sub-10 ns noise pulses - prevents false triggering in electrically noisy environments like variable-frequency drives. |
Applications
| Motor Drive Control | Medical Isolated Data Acquisition |

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 |
|---|---|---|---|
| SI8642ED-B-IS | 4-channel, 5 kVRMS, 100 Mbps max, 2.5 ns PWD, 3.3 V only supply range | Lacks 5 V operation and mixed-voltage capability; no output enable pin | Prefer when system operates exclusively at 3.3 V and requires marginally higher speed without tri-state control. |
| ISO6742QDWR | 4-channel, 5 kVRMS, 50 Mbps max, 3 ns PWD, 1.71–5.5 V supply, integrated LDO on side 2 | Lower data rate; includes regulated 3.3 V output but adds complexity and thermal load | Choose when downstream logic requires regulated side-2 power and 90 Mbps is not required. |
Compared with SI8642ED-B-IS and ISO6742QDWR, ADUM4402BRIZ uniquely combines 90 Mbps speed, dual-supply flexibility (3.3 V/5 V), output enable control, and <2 ns timing precision-making it optimal for high-fidelity motor control and medical diagnostics where timing integrity and voltage interoperability are critical.

FAQ
What safety certifications does ADUM4402BRIZ hold?
ADUM4402BRIZ holds UL 1577 (5000 VRMS for 1 min), DIN EN IEC 60747-17 (VDE 0884-17) reinforced insulation (645 Vpeak), IEC/CSA 60601-1 (2 MOPP), and IEC/EN/CSA 62368-1 approvals. These certifications apply specifically to the RI-16 package variant denoted by the 'R' in ADUM4402BRIZ, confirming suitability for medical and industrial safety-critical designs.
How does ADUM4402BRIZ handle power loss on one side?
ADUM4402BRIZ incorporates a patented refresh feature that maintains correct output states during input-side power loss or inactivity. When VDD1 is unpowered, outputs on Side 2 return to their last valid state within 1 µs after VDD1 restoration. If VDD2 is lost, outputs enter indeterminate state unless VE2 is held low to force high-impedance mode-ensuring predictable behavior during asymmetric power sequencing.
Can ADUM4402BRIZ operate with different supply voltages on each side?
Yes, ADUM4402BRIZ supports mixed-supply operation: VDD1 and VDD2 can independently range from 3.0 V to 5.5 V. Verified configurations include 5 V/3.3 V and 3.3 V/5 V, enabling seamless level translation between legacy 5 V controllers and modern 3.3 V peripherals without external level shifters-critical for upgrading existing industrial systems.
What is the function of the VE2 pin on ADUM4402BRIZ?
The VE2 pin on ADUM4402BRIZ is an active-high output enable control for Side 2 outputs (VOA–VOD). When VE2 is high or floating, outputs drive normally; when VE2 is low, all Side 2 outputs transition to high-impedance within 8 ns. This enables bus arbitration, fault containment, and power-saving modes in multi-master systems-distinct from ADUM4400/4401 which lack dedicated output enable on Side 2.
Does ADUM4402BRIZ require external components for basic operation?
No, ADUM4402BRIZ operates with only bypass capacitors (0.1 µF ceramic per VDD pin) and proper PCB layout per AN-793 guidelines. It integrates input glitch filtering, refresh circuitry, and ESD protection-eliminating need for external RC networks, pull-ups, or discrete protection devices in most applications. The RI-16 package's 8.7 mm creepage also removes requirement for slotting or spacing enhancements in high-voltage layouts.
