ADUM1300WSRWZ33-RL

Overview

The ADUM1300WSRWZ33-RL is a triple-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 1 Mbps. The device features a 2500 Vrms isolation voltage and a common-mode transient immunity (CMTI) of 25 kV/µs. Packaged in a 16-SOIC format with a 7.50 mm width, it is designed for robust performance across an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation between circuits using on-chip transformer technology
• Supports unidirectional signal transmission across three independent channels
• Ensures high noise immunity with specified common-mode transient rejection capabilities

Applications

• Industrial automation control systems requiring isolated communication
• Medical equipment needing patient isolation barriers
• Power electronics monitoring interfaces

Procurement Notes

Verify the specific suffix '33' against official Analog Devices documentation to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with the 16-SOIC footprint during PCB layout. Confirm that the 1 Mbps data rate meets system timing constraints before finalizing component selection.

Selection Notes

Select this component when a triple-channel solution is required with moderate data speeds and high isolation voltage. Compare propagation delay and power consumption against other ADuM series devices if lower latency or reduced current draw is critical for the application.

Part Context

This part belongs to the ADUM1300 family of general-purpose digital isolators. It offers a compact alternative to traditional optocouplers by integrating magnetic coupling technology directly into the silicon die, providing improved reliability and smaller form factors for modern electronic designs.

Replacement Considerations

ADUM1300WTRWZ is listed as a parameter-equivalent substitute.
