ADIADUM4160BRIZ-RL
Overview
The ADUM4160BRIZ-RL is a high-performance USB digital isolator based on Analog Devices iCoupler technology, providing 5000Vrms isolation for USB 2.0 communication. It supports bidirectional data transfer at Low Speed (1.5 Mbps) and Full Speed (12 Mbps) without the need for complex external software or drivers. This IC is specifically designed to eliminate ground loops and protect sensitive upstream hardware from high-voltage transients and noise.
Why Choose This Part
It offers superior common-mode transient immunity (CMTI) of over 25kV/us, ensuring reliable data transmission even in electrically noisy environments. The 5000Vrms isolation rating meets stringent UL 1577 standards, while the wide 3.1V to 5.5V supply range allows for flexible power configurations in various embedded systems.
Applications
Key Specifications
Getting Started
When designing with the ADUM4160BRIZ-RL, ensure that the upstream and downstream power supplies are independently bypassed with 0.1uF ceramic capacitors located near the VDD pins. Set the SPU and SPD pins to match the desired data rate (1.5 Mbps or 12 Mbps), and refer to the EVAL-ADuM4160EBZ evaluation board for optimized PCB layout patterns that maintain creepage and clearance requirements.
