ADUM340E1WBRQZ

Overview

The ADUM340E1WBRQZ is a four-channel digital isolator from Analog Devices, featuring iCoupler technology for signal transmission across isolation barriers. It operates with a single 2.7V to 5.5V supply and provides bidirectional channel functionality. The device offers high common-mode transient immunity of 50kV/us and supports data rates up to 150Mbps per channel. Packaged in a 16-lead SOIC_W narrow body, it ensures reliable operation over an industrial temperature range of -40°C to +125°C.

Feature Summary

• Utilizes iCoupler technology for integrated transformer-based isolation without external components.
• Provides bidirectional signal transmission across the isolation barrier for each channel.
• Features high common-mode transient immunity to ensure signal integrity in noisy environments.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe isolation barriers
• Power management circuits with isolated feedback loops

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the voltage ratings and isolation specifications align with the system design requirements. Ensure compliance with RoHS directives if applicable. Check for any recent updates to the datasheet regarding mechanical dimensions or thermal characteristics before finalizing procurement.

Selection Notes

Select this component when high-speed bidirectional isolation is needed within a compact footprint. Consider the operating voltage range and data rate requirements against the application's performance needs. Evaluate the thermal management capabilities given the wide operating temperature range. Compare pinout compatibility with existing designs to minimize redesign efforts.
