Product details
Overview
ADUM1300CRWZ from Analog Devices is a triple-channel digital isolator based on iCoupler® transformer technology, providing galvanic isolation between microcontroller and peripheral interfaces in industrial and automotive systems. It delivers 90 Mbps data rate, <2 ns pulse width distortion, and 2 ns channel-to-channel matching at 125°C, with bidirectional signal transmission across a 2500 Vrms isolation barrier for SPI and RS-485 transceiver isolation.
For engineers reviewing the ADUM1300CRWZ datasheet, ADUM1300CRWZ pinout, ADUM1300CRWZ application, or ADUM1300CRWZ equivalent, this page provides verified timing specs, SOIC-16W package layout, level translation capability (3 V/5 V), high CMTI (>25 kV/µs), and validated alternatives for high-speed isolated communication designs.
Technical Context
The ADUM1300CRWZ implements three independent unidirectional isolation channels using monolithic air-core transformers, enabling precise dc-corrected signal transfer without optocoupler drift or aging. Its patented refresh circuit maintains logic state integrity during dc or idle conditions and under asymmetric supply loss.
It supports mixed-voltage operation (2.7–5.5 V per side), delivering 3 V/5 V level translation while maintaining sub-2 ns timing precision and <10 ns propagation delay skew across all channels at 90 Mbps - confirmed for CRW-grade performance at 125°C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8631BB-B-IS | Capacitive isolation; 100 Mbps max rate; 2.5 kVrms isolation; 16-pin SOIC narrow (3.9 mm) | Limited to 105°C ambient; no integrated refresh; lower CMTI (15 kV/µs) | Prefer for cost-sensitive consumer applications where 125°C operation and highest CMTI are not required |

FAQ
What is the maximum guaranteed data rate for ADUM1300CRWZ?
The ADUM1300CRWZ is specified for a maximum data rate of 90 Mbps (NRZ) with pulse width distortion ≤2 ns, verified across temperature (−40°C to +125°C) and supply ranges (2.7–5.5 V per side). This rating is guaranteed per the CRW grade qualification in the Rev. M datasheet, Table 1 and Table 3 switching specifications.
Does ADUM1300CRWZ support level translation between 3.3 V and 5 V domains?
Yes, ADUM1300CRWZ supports true bidirectional level translation: VDD1 may operate at 3.3 V while VDD2 operates at 5 V (or vice versa), with logic thresholds scaling accordingly (VIH = 1.6 V at 3 V side, 2.0 V at 5 V side). This is explicitly characterized in Table 3 for mixed-supply operation and enables direct interface without external level shifters.
How does the refresh feature in ADUM1300CRWZ improve system reliability?
The patented refresh feature in ADUM1300CRWZ continuously monitors input state and retransmits static logic levels across the isolation barrier - ensuring correct output behavior even during extended dc input conditions or loss of one supply rail. This eliminates output drift or metastability seen in optocouplers and basic capacitive isolators, directly enhancing functional safety in BMS and motor control applications.
What safety certifications apply to ADUM1300CRWZ?
ADUM1300CRWZ carries UL 1577 (2500 Vrms for 1 minute), DIN EN IEC 60747-17 (VDE 0884-17, VIORM = 560 Vpeak), IEC/EN/CSA 62368-1, EN 60950-1, IEC/CSA 60601-1, and IEC/CSA 61010-1. These are documented in the Regulatory Information section (page 20) and Insulation Characteristics table (page 21) of the Rev. M datasheet.
Can ADUM1300CRWZ replace optocouplers in existing designs without layout changes?
ADUM1300CRWZ uses a standard 16-lead SOIC wide-body footprint (7.5 mm × 10.3 mm) identical to many industry-standard optocouplers and digital isolators. Pin compatibility is confirmed via the Pin Configurations section (page 24) - VDD1/GND1/VDD2/GND2 and signal pins align functionally, enabling drop-in replacement where timing and drive strength requirements match.
