NRND3,284 in stock

Overview

The ADUM110N0BRZ-RL7 is a high-speed, single-channel digital isolator utilizing Analog Devices' iCoupler technology to provide 3000Vrms isolation. It supports data rates up to 150Mbps and operates across a wide supply range of 1.7V to 5.5V, making it ideal for level translation and noise immunity in harsh environments. With a high common-mode transient immunity (CMTI) of up to 100kV/us, it ensures reliable signal integrity in high-power switching applications.

Why Choose This Part

This isolator offers a very low propagation delay and 150Mbps throughput for high-performance timing requirements. Its low power consumption of 0.7mA to 3.4mA and high CMTI of 100kV/us provide superior robustness compared to traditional optocouplers. Additionally, the fail-safe low design ensures the output stays in a known state during loss of input power.

Applications

Industrial Fieldbus Isolation
Protecting logic controllers from high-voltage transients in RS-485, CAN, or Profibus networks.
Isolated SPI/UART Communication
Providing galvanic isolation for high-speed serial data links between microcontrollers and peripherals.
Motor Control Gate Drive
Isolating PWM signals sent to power stages to prevent ground loops and protect low-voltage control circuitry.
Battery Management Systems
Maintaining safe communication across high-voltage battery stacks in electric vehicle or storage applications.

Getting Started

Designers should place 0.1uF bypass capacitors as close as possible to the VDD1 and VDD2 pins to maintain signal integrity. For evaluation, the EVAL-ADuM110N0EBZ board provides a ready-to-use platform for testing transient immunity and propagation delay. Ensure that the PCB layout maintains the required creepage and clearance distances for 3000Vrms isolation rating.
