ADUM110N1BRZ

Overview

The ADUM110N1BRZ is a single-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 3000Vrms isolation voltage with a data rate of 150Mbps and 75kV/µs common-mode transient immunity (CMTI). The device operates on a supply voltage range of 1.7V to 5.5V, featuring maximum propagation delays of 13ns for both high-to-low and low-to-high transitions. Typical rise and fall times are 2.5ns, with a maximum pulse width distortion of 3ns. It is housed in an 8-SOIC package and supports general-purpose applications across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates iCoupler chip-scale transformer technology for robust magnetic signal coupling
• Provides high-speed unidirectional data transmission with significant common-mode noise rejection
• Supports wide supply voltage operation compatible with various logic families

Applications

• General-purpose digital isolation in industrial control systems
• Isolation for sensor interfaces requiring high noise immunity
• Communication bus isolation in embedded systems

Procurement Notes

Verify the specific suffix '1' indicates the correct directionality configuration for your circuit design. Confirm the 8-SOIC package dimensions match your PCB footprint requirements. Ensure the 3000Vrms isolation rating meets the safety standards of your target application environment. Check RoHS compliance status if required by your manufacturing regulations.

Selection Notes

Select this component when a single channel of high-speed isolation is required. The 150Mbps data rate suits most standard digital communication protocols. Consider the 75kV/µs CMTI for environments with high dv/dt noise. Compare power consumption against other iCoupler variants if energy efficiency is critical. Verify that the 1.7V minimum supply voltage aligns with your system's logic levels.

Part Context

This part belongs to the ADuM110N family of single-channel digital isolators from Analog Devices. It shares the core iCoupler technology found in broader series like the ADUM1200 or ADUM163N but is optimized for single-channel use. The family emphasizes compact size and reliability through silicon-based magnetic coupling rather than optical components.
