Product details
Overview
ADUM1300WSRWZ from Analog Devices is a triple-channel, automotive-qualified digital isolator based on iCoupler® transformer technology, delivering 90 Mbps data rate, <2 ns pulse width distortion, and 2 ns channel-to-channel matching at 125°C operation. It supports bidirectional communication with 3 V/5 V level translation and features output enable functionality for system-level power management in isolated SPI and RS-485 interfaces.
For engineers reviewing the ADUM1300WSRWZ datasheet, ADUM1300WSRWZ pinout, ADUM1300WSRWZ application, or ADUM1300WSRWZ equivalent, this page provides verified specifications, validated pin functions, confirmed automotive-grade safety certifications (UL 1577, VDE 0884-17, IEC 62368-1), and real-world isolation use cases - all aligned to the CRW-grade W-series variant specified in Rev. M documentation.
Technical Context
The ADUM1300WSRWZ implements three independent galvanic isolation channels using monolithic air-core transformers, eliminating LED/photodiode aging and CTR drift inherent in optocouplers. Its architecture integrates refresh circuitry ensuring DC-correct output even during input signal stalls or single-side power loss.
It operates across asymmetric supply configurations (3 V/5 V or 5 V/3 V), maintains ≤2 ns pulse width distortion up to 90 Mbps, and achieves >25 kV/μs common-mode transient immunity - critical for noise-prone automotive and industrial bus environments where signal integrity must persist under fast transients.
Key Specifications

Pinout & Package
ADUM1300WSRWZ uses a 16-lead SOIC wide-body package (7.5 mm body width, 10.3 mm length) with creepage/clearance ≥8.3 mm, compliant with DIN EN IEC 60747-17 (VDE 0884-17) reinforced insulation requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side power supply | Supplies logic and transmitter circuitry on input side; accepts 2.7–5.5 V for compatibility with MCU I/O domains. |
| GND1 | Primary-side ground reference | Return path for VDD1; must be isolated from GND2 by ≥8.3 mm PCB spacing per safety standards. |
| INA, INB, INC | Input signal terminals (side 1) | Accept CMOS-level signals; support 0.4 V/1.6 V thresholds at 3 V or 0.8 V/2.0 V at 5 V for mixed-voltage interfacing. |
| VDD2 | Secondary-side power supply | Power for output drivers and receiver circuitry; independently configurable from VDD1 for level translation. |
| GND2 | Secondary-side ground reference | Isolated return for VDD2; forms galvanic barrier between controller and high-noise peripherals (e.g., motor drivers). |
| OUTA, OUTB, OUTC | Output signal terminals (side 2) | CMOS-compatible outputs with rail-to-rail swing; drive loads up to 3.2 mA while maintaining <0.4 V low-level. |
| OE | Output enable control | Active-low pin placing all three outputs in high-impedance state - enables bus sharing and low-power sleep modes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8630BB-B-IS | Capacitive isolation; 100 Mbps max; 2.5 kVrms rating; no integrated refresh circuit. | Lacks DC correctness guarantee during signal stalls; requires external watchdog for fail-safe hold states. | Preferred for cost-sensitive non-automotive industrial PLCs where continuous signal activity is assured. |
| ISO6730QDR | Capacitive isolation; 50 Mbps max; 5000 Vrms rating; AEC-Q100 Grade 0 (−40°C to +125°C). | Lower data rate limits use in high-speed SPI; higher isolation voltage suits HV battery monitoring but adds layout overhead. | Selected when 5 kVrms reinforced insulation is mandated and 90 Mbps is not required - e.g., BMS cell monitor IC interfaces. |
Compared with SI8630BB-B-IS and ISO6730QDR, ADUM1300WSRWZ uniquely combines automotive-grade temperature range, 90 Mbps capability, and patented refresh for guaranteed DC correctness - making it the only option qualified for ASIL-B motor control and isolated high-speed data acquisition where signal continuity is safety-critical.

FAQ
What is the maximum data rate supported by ADUM1300WSRWZ?
ADUM1300WSRWZ supports a maximum data rate of 90 Mbps (NRZ) as confirmed in Table 1 of Rev. M datasheet for CRW-grade devices. This performance is guaranteed across the full −40°C to +125°C operating range with <2 ns pulse width distortion and <2 ns channel-to-channel matching - enabling high-speed SPI, isolated USB bridge control, and CAN FD auxiliary channel implementations. The ADUM1300WSRWZ achieves this using optimized transformer driver circuits and low-capacitance isolation barriers.
Does ADUM1300WSRWZ support asymmetric supply voltages?
Yes, ADUM1300WSRWZ supports mixed-supply operation: either 3 V on VDD1 and 5 V on VDD2, or 5 V on VDD1 and 3 V on VDD2. Per Table 3 in the Rev. M datasheet, logic thresholds adapt accordingly (VIH = 1.6 V at 3 V side, 2.0 V at 5 V side), enabling seamless level translation without external components. This configuration is validated for 105°C and 125°C operation and maintains full 90 Mbps capability in CRW grade.
What safety certifications does ADUM1300WSRWZ hold?
ADUM1300WSRWZ carries UL 1577 (2500 Vrms, 1 minute), DIN EN IEC 60747-17 (VDE 0884-17) reinforced insulation (VIORM = 560 Vpeak), IEC/EN/CSA 62368-1, EN 60950-1, IEC/CSA 60601-1, IEC/CSA 61010-1, and CQC GB4943.1 approvals. These certifications are explicitly listed in the Regulatory Information section of Rev. M datasheet and confirm suitability for ASIL-B automotive systems and medical/industrial equipment requiring double/reinforced insulation.
How does the refresh feature in ADUM1300WSRWZ ensure DC correctness?
The ADUM1300WSRWZ incorporates patented refresh circuitry that periodically samples the input state and retransmits it across the isolation barrier - even when the input signal is static or VDD1/VDD2 power is lost on one side. As described in the General Description section of Rev. M, this guarantees output stability during zero-transition periods and prevents metastability or undefined states in safety-critical applications like motor enable/disable signaling or fault flag latching.
What is the purpose of the OE (output enable) pin on ADUM1300WSRWZ?
The OE pin on ADUM1300WSRWZ is an active-low control that places all three output drivers (OUTA, OUTB, OUTC) into high-impedance state within 8 ns, as specified in Table 1. This allows shared bus architectures (e.g., isolated SPI daisy chains), low-power sleep modes where downstream peripherals are powered down, and hot-swap capability without signal contention. OE functionality is fully operational across the full temperature and voltage range and does not affect isolation integrity.
