Product details
Overview
ADUM2402BRWZ from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation, configured with two forward and two reverse bidirectional channels (2/2 directionality), rated for 10 Mbps data rate, 2.7–5.5 V dual-supply operation, and 5000 Vrms reinforced isolation in a 16-lead SOIC wide-body package. It enables level translation between 3 V and 5 V domains in motor drive gate driver interfaces.
For engineers reviewing the ADUM2402BRWZ datasheet, ADUM2402BRWZ pinout, ADUM2402BRWZ application, or ADUM2402BRWZ equivalent, this part delivers precise timing (3 ns pulse width distortion, 3 ns codirectional channel matching), high common-mode transient immunity (>25 kV/µs), and output enable control - critical for IGBT/SiC gate driver feedback loops and isolated ADC/DAC communication in industrial power systems.
Technical Context
The ADUM2402BRWZ implements four independent galvanically isolated signal paths using monolithic air-core transformers, eliminating LED/photodiode aging and CTR drift inherent to optocouplers. Its architecture supports asymmetric supply configurations (e.g., 5 V primary / 3 V secondary) while maintaining logic thresholds compatible with both voltage domains.
It integrates a patented refresh circuit ensuring DC correctness during idle periods and power transitions, and features separate output-enable (OE) inputs per side for dynamic channel control. Propagation delay skew is specified at ≤22 ns across all channels under 10 Mbps operation, enabling synchronized sampling in isolated current sensing subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 10 Mbps - guarantees ≤3 ns pulse width distortion for clean NRZ signal integrity in motor control PWM feedback |
| Isolation Rating | 5000 Vrms for 1 minute - meets reinforced insulation requirements for UL 1577 and IEC/EN/CSA 62368-1 safety compliance |
| Supply Range | 2.7 V to 5.5 V per side - enables 3 V/5 V level translation across isolation barrier without external level shifters |
| Pulse Width Distortion | ≤3 ns - ensures minimal duty cycle error in isolated PWM or clock distribution applications |
| Codirectional Matching | ≤3 ns - allows tightly synchronized sampling of multiple isolated analog channels (e.g., three-phase current sensing) |
| Common-Mode Immunity | >25 kV/µs - sustains reliable operation in high-dV/dt environments like IGBT switching nodes |
| Propagation Delay | 20–50 ns - low and bounded latency suitable for real-time closed-loop control timing budgets |
| Operating Temperature | −40°C to +105°C - supports deployment in industrial motor drives and power supply control boards |
Pinout & Package
ADUM2402BRWZ is housed in a 16-lead SOIC wide-body (RW-16) package with 7.6 mm creepage and clearance, optimized for high-voltage isolation. Pin functions are validated per Analog Devices' Rev. H datasheet Figure 16 (Pin Configurations and Function Descriptions).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side supply | Power for input-side logic and transformers; accepts 2.7–5.5 V; decoupling required near pin |
| GND1 | Primary-side ground | Reference for inputs A/B/C/D and OE1; must be separated from secondary ground by isolation barrier |
| VA, VB | Forward-direction inputs | Signals transmitted from primary to secondary side (VDD1 → VDD2 domain) |
| VC, VD | Reverse-direction inputs | Signals transmitted from secondary to primary side (VDD2 → VDD1 domain) |
| OE1 | Primary-side output enable | Active-low control disabling VA/VB outputs; used for bus arbitration or fault shutdown |
| VDD2 | Secondary-side supply | Power for output-side logic; independent 2.7–5.5 V rail; enables level translation |
| GND2 | Secondary-side ground | Reference for outputs YA/YB/YC/YD and OE2; isolated from GND1 |
| YA, YB | Forward-direction outputs | Isolated replicas of VA/VB; drive secondary-side logic or gate drivers |
| YC, YD | Reverse-direction outputs | Isolated replicas of VC/VD; feed back status or control signals across barrier |
| OE2 | Secondary-side output enable | Active-low control disabling YC/YD outputs; supports bidirectional bus management |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional 2/2 channel configuration | Two dedicated forward (A/B→Y/A/Y/B) and two reverse (C/D→Y/C/Y/D) paths - simplifies isolated bidirectional communication without external routing logic |
| Output enable per side | Independent OE1 and OE2 pins allow dynamic channel disable for power gating or fault containment in multi-isolator systems |
| DC-correct refresh circuit | Patented internal refresh maintains output state during static input conditions or power-up - eliminates need for external watchdog or keep-alive signals |
| Low temperature drift | 5 ps/°C propagation delay variation - ensures timing stability across industrial temperature range without calibration |
| Mixed-voltage operation | Validated 3 V/5 V and 5 V/3 V supply combinations - enables direct interfacing between legacy 5 V controllers and modern 3.3 V sensors or ADCs |

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 | Capacitive isolation; 10 Mbps; 5000 Vrms; 16-pin SOIC; no integrated refresh circuit | Lacks DC-correct refresh - requires periodic input toggling to maintain output state | Prefer ADUM2402BRWZ when static signal integrity or power-up reliability is critical; SI8642ED-B-IS acceptable for continuously active data links |
| ISO6742FDWR | Capacitive isolation; 50 Mbps; 5000 Vrms; 16-pin SOIC; 2/2 channel directionality; no OE pins | No output enable functionality - limits use in bus-arbitrated or fault-containment topologies | Select ADUM2402BRWZ when dynamic channel disable is needed; ISO6742FDWR suits higher-speed unidirectional-heavy applications without OE requirement |
Compared with SI8642ED-B-IS and ISO6742FDWR, ADUM2402BRWZ uniquely combines guaranteed DC correctness, dual output-enable control, and 3 ns timing precision - making it optimal for safety-critical motor control and medical feedback loops where deterministic behavior under static or transient conditions is non-negotiable.

FAQ
What is the maximum data rate supported by ADUM2402BRWZ?
ADUM2402BRWZ supports a maximum data rate of 10 Mbps, verified under load conditions (CL = 15 pF, CMOS levels) with guaranteed ≤3 ns pulse width distortion. This rating applies across its full operating temperature range (−40°C to +105°C) and supply range (2.7 V to 5.5 V per side). Higher-speed variants like ADUM2402CRWZ support up to 90 Mbps but are not drop-in replacements due to differing AC characteristics and qualification.
Does ADUM2402BRWZ require external components for basic operation?
Yes, ADUM2402BRWZ requires 0.1 µF ceramic bypass capacitors placed as close as possible to each VDD pin (VDD1 and VDD2) relative to their respective grounds (GND1 and GND2). No pull-up/pull-down resistors are needed on inputs or outputs, as logic thresholds are internally defined. The output enable (OE1/OE2) pins default to enabled (active-low logic) when left unconnected, but should be actively driven for deterministic control.
Can ADUM2402BRWZ operate with different supply voltages on each side?
Yes, ADUM2402BRWZ supports mixed-supply operation: either 5 V on VDD1 and 3.3 V on VDD2, or 3.3 V on VDD1 and 5 V on VDD2. Input thresholds adapt accordingly (VIH = 2.0 V for 5 V side, 1.6 V for 3 V side), and output drive strength scales with the local VDD. This eliminates external level shifters in heterogeneous voltage domain interfaces such as microcontroller-to-ADC or FPGA-to-gate-driver links.
How does the refresh feature in ADUM2402BRWZ work?
ADUM2402BRWZ incorporates a patented internal refresh circuit that periodically samples and retransmits the last valid input state during extended static conditions or power transitions. This ensures outputs remain stable and correct even when inputs are held constant for seconds or minutes - a key advantage over optocouplers and some capacitive isolators that drift or fail to retain state without toggling. The refresh operates autonomously with no external intervention required.
What safety certifications apply to ADUM2402BRWZ?
ADUM2402BRWZ (RW-16 package) is certified to UL 1577 (5000 Vrms/1 min), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (medical), IEC/CSA 61010-1 (industrial), CQC GB 4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 V peak. These approvals validate its suitability for reinforced insulation in end-equipment requiring functional safety, including motor drives, power supplies, and diagnostic imaging systems.
