ADUM1300CRW

Overview

The ADUM1300CRW is a triple-channel digital isolator from Analog Devices, utilizing iCoupler technology which combines high-speed CMOS core circuitry with monolithic transformer coupling. This device provides electrical isolation for three independent signal channels in a single package. It supports unidirectional data transmission with a maximum data rate of 90 Mbps and offers a common-mode transient immunity (CMTI) of 25 kV/µs. The component operates within a supply voltage range of 2.7 V to 5.5 V and features a propagation delay of approximately 27 ns. It is housed in a 16-lead SOIC package.

Feature Summary

• Integrates three isolated channels using proprietary iCoupler magnetic coupling technology
• Provides robust signal integrity with high common-mode transient immunity
• Supports high-speed digital communication up to 90 Mbps per channel
• Enables compact system design by replacing bulky discrete isolation components

Applications

• General-purpose multichannel isolation in industrial systems
• Isolation for microcontroller and DSP interfaces
• Data acquisition systems requiring galvanic isolation
• Power management circuits with isolated feedback paths

Procurement Notes

Verify the specific suffix of the part number when ordering, as variants such as CRWZ or CRWZ-RL may differ in packaging or manufacturing status. Confirm availability through authorized distributors, as some versions may be discontinued or have limited stock. Ensure the selected variant matches the required lead time and reel specifications for your assembly process.

Selection Notes

Select this component when three isolated bidirectional or unidirectional channels are required in a space-constrained design. Consider the 90 Mbps data rate limit and 25 kV/µs CMTI specification against your application's noise environment. Verify that the 16-lead SOIC package footprint fits your PCB layout constraints and that the operating temperature range meets your environmental requirements.

Part Context

The ADUM1300CRW belongs to the ADuM130x family of triple-channel digital isolators from Analog Devices. These devices are designed to replace traditional optocouplers and relay-based isolation solutions. The family leverages silicon and polymer technology to create integrated isolation barriers, offering improved performance, reliability, and size reduction compared to legacy technologies.

Replacement Considerations

The ADUM1300CRW-RL is listed as an obsolete version with the ADUM1300CRWZ-RL identified as a direct substitute. Verify pinout compatibility and parameter equivalence before transitioning to the replacement part number.
