ADUM1400BRW

Overview

The ADUM1400BRW is a quad-channel digital isolator utilizing iCoupler technology. It features four unidirectional channels with a 4/0 configuration. The device provides 2500Vrms isolation voltage and supports data rates up to 10Mbps. Key electrical parameters include a maximum propagation delay of 100ns, typical rise/fall times of 2.5ns, and a minimum common-mode transient immunity of 25kV/µs. It operates on a supply voltage range of 3V to 5.5V and functions within a temperature range of -40°C to 125°C.

Feature Summary

• Integrates four independent digital isolation channels in a single package
• Employs magnetic coupling technology for signal transmission without external transformers
• Provides high common-mode transient immunity for noise rejection
• Supports bidirectional power delivery across the isolation barrier

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing reinforced insulation barriers
• Power management circuits with isolated feedback loops
• Data acquisition systems interfacing high-voltage sensors

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent package degradation during assembly processes.

Selection Notes

Select this component when four unidirectional isolated signals are required within a compact footprint. Consider the 10Mbps data rate limit and 100ns propagation delay for timing-sensitive designs. Evaluate thermal performance within the specified operating range and ensure PCB layout accommodates the SOIC-16 package dimensions.
