ADUM1300WTRWZ33

Overview

The ADUM1300WTRWZ33 is a triple-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides bidirectional signal isolation with a rated isolation voltage of 2500 Vrms and a minimum common-mode transient immunity of 25 kV/µs. The device operates on a single power supply ranging from 2.7 V to 5.5 V, drawing a typical operating current of 57 mA. It supports data rates up to 10 Mbps with a maximum propagation delay of 32 ns and rise/fall times of 2.5 ns. Packaged in a 16-lead SOIC, it functions within an industrial temperature range of -40°C to +125°C.

Feature Summary

• Integrates three independent isolation channels using proprietary iCoupler magnetic coupling technology for robust signal transmission.
• Delivers high-speed performance with a 10 Mbps data rate capability and low propagation delay characteristics.
• Ensures electrical safety through a 2500 Vrms isolation rating and superior common-mode transient immunity.
• Supports flexible logic interface requirements with bidirectional channel configuration across the entire supply voltage range.

Applications

• Industrial automation systems requiring galvanic isolation between control units and sensors
• Medical equipment interfaces demanding high isolation integrity and patient safety compliance
• Automotive electronics applications necessitating reliable communication across different ground potentials

Procurement Notes

Verify the specific suffix '33' against official Analog Devices documentation to confirm pinout and functional equivalence, as suffixes often denote specific packaging or qualification variations. Confirm RoHS compliance status and check for active manufacturing status, as this part may be obsolete or subject to replacement by newer revisions. Ensure the required package type matches the design constraints before finalizing procurement orders.

Selection Notes

Select this component when a triple-channel solution is required for cost-effective isolation in space-constrained designs. It is suitable for applications needing bidirectional data transfer without isolated power supplies. Consider the 16-SOIC package dimensions and thermal characteristics during PCB layout. Evaluate the 57 mA supply current against system power budgets compared to lower-power alternatives if energy efficiency is critical.
