ADUM140E1BRWZ

Overview

The ADUM140E1BRWZ is a quad-channel digital isolator utilizing iCoupler technology, integrating high-speed CMOS with monolithic air-core transformer technology. It provides 3750 Vrms isolation voltage and supports data rates up to 150 Mbps. The device features unidirectional channels with a maximum propagation delay of 13 ns and typical rise/fall times of 2.5 ns. It operates on a supply voltage range of 1.7 V to 5.5 V with a maximum operating current of 12 mA per channel. The component offers a common-mode transient immunity of 75 kV/µs and functions within an extended temperature range of -40°C to +125°C.

Feature Summary

• Integrates four independent unidirectional signal paths using magnetic coupling technology for robust electrical isolation.
• Provides high common-mode transient immunity to maintain signal integrity in noisy environments.
• Supports precise timing characteristics with low pulse width distortion and tight channel-to-channel matching.
• Operates across a wide supply voltage range to accommodate various logic levels without external level shifters.

Applications

• Industrial field bus isolation
• SPI interface and data converter isolation
• Automotive systems requiring multichannel isolation

Procurement Notes

Verify the specific suffix 'BRWZ' to confirm the 16-lead SOIC wide body package (7.50 mm width) and tape-and-reel or tube packaging options. Ensure the order matches the required insulation voltage rating of 3750 Vrms. Confirm RoHS compliance status and moisture sensitivity level requirements before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required in a compact footprint. It is suitable for designs needing high common-mode transient immunity exceeding standard optocoupler capabilities. Consider the 1.7 V to 5.5 V supply range for compatibility with diverse logic families. Evaluate the 150 Mbps data rate against system throughput requirements to ensure adequate performance margins.

Part Context

This part belongs to the ADuM140E series of quad-channel digital isolators from Analog Devices. It shares architectural similarities with the ADUM1401 but differs in insulation voltage ratings and specific package configurations. The series leverages iCoupler technology to replace traditional optocouplers, offering improved speed and lower power consumption while maintaining safety certifications.
