Overview
The ADUM1100BRZ is a single-channel digital isolator utilizing Analog Devices iCoupler technology, which integrates high-speed CMOS logic with monolithic air-core transformer coupling. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 Mb/s. The device provides an isolation voltage of 2500 Vrms and exhibits a typical propagation delay of 18 ns. It functions in unidirectional mode with a maximum power dissipation of 240 mW and maintains operation across an extended temperature range from -40°C to +125°C.
Feature Summary
- Integrates high-speed CMOS technology with monolithic air-core transformer coupling for signal transmission.
- Provides robust galvanic isolation between input and output circuits without magnetic core saturation risks.
- Supports general-purpose digital signal isolation with low power consumption characteristics.
Applications
- General-purpose digital signal isolation in industrial systems
- Isolation barriers in measurement and control circuits
- Power management interface isolation
Procurement Notes
Verify the specific package variant, as the BRZ suffix denotes SOIC-8 tube packaging. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected component matches the required data rate and isolation voltage specifications for the target application environment.
Selection Notes
Select this component when a single-channel, unidirectional isolator is required for signals up to 100 Mb/s. It is suitable for applications needing 2500 Vrms isolation with low propagation delay. Consider alternative channel counts or bidirectional variants if the system design requires multi-channel or two-way communication capabilities.
Part Context
This part belongs to the ADuM1100 series of iCoupler digital isolators. The series leverages proprietary silicon and polymer technology to replace traditional optocouplers, offering improved reliability and performance in compact surface-mount packages.
FAQ
What is the common-mode transient immunity (CMTI) specification?
The datasheet specifies a CMTI of 25 kV/µs for the ADUM1100BRZ.
