ADUM1400WTRWZ55

Overview

The ADUM1400WTRWZ55 is a quad-channel digital isolator manufactured by Analog Devices Inc. It provides four independent channels for signal isolation with a data rate of 10 Mbps and a common-mode transient immunity (CMTI) of 25 kV/µs. The device operates on a supply voltage range of 2.7 V to 5.5 V and features a propagation delay of 2.5 ns. It is housed in a 16-pin SOIC package with a width of 7.50 mm, designed for surface mount installation.

Feature Summary

• Provides four isolated bidirectional or unidirectional channels for digital signal transmission
• Utilizes iCoupler technology for robust magnetic coupling isolation
• Offers high common-mode transient immunity for noise rejection
• Supports wide operating temperature ranges for industrial applications

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safety-certified signal isolation
• Power electronics control circuits with high voltage differences
• Data acquisition systems with multiple isolated inputs

Procurement Notes

Verify the specific suffix WTRWZ55 against official Analog Devices documentation to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with your PCB footprint and reflow soldering profile. Check for RoHS compliance status in the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when four isolated channels are required within a single package. Consider the 10 Mbps data rate and 25 kV/µs CMTI for high-speed noisy environments. Compare power consumption and propagation delay against other iCoupler variants if lower latency or reduced current draw is critical for your specific application constraints.

Part Context

This part belongs to the ADUM1400 family of quad-channel digital isolators from Analog Devices. These devices are designed to replace traditional optocouplers, offering superior performance in speed, power consumption, and reliability. The family includes various packages and ratings to suit different isolation voltage and channel configuration needs.

Replacement Considerations

Check for direct replacements like ADUM1400WTRWZ or ADUM1400WSRWZ, ensuring voltage and speed specifications align. Verify that any substitute maintains the same 16-SOIC package dimensions and pin configuration to avoid PCB redesign.
