Overview

The ADUM161N1BRZ is a 6-channel digital isolator based on Analog Devices' iCoupler technology, offering 5 forward and 1 reverse channel. It provides 3000Vrms isolation and a high data rate of 150Mbps while maintaining a low propagation delay of 13ns. This device is designed to provide robust signal isolation without the size and power constraints of traditional optocouplers.

Why Choose This Part

The component features a high CMTI of 100kV/us and low dynamic power consumption of 3.2mA at 5V. Its 150Mbps bandwidth and tight 13ns propagation delay make it suitable for high-speed synchronous serial interfaces, while the 5/1 channel configuration is optimized for common bidirectional sensor interfaces.

Applications

Isolated SPI Communications
Ideal for isolating SPI buses where four forward channels handle CS, SCLK, and MOSI, while the reverse channel handles MISO.
Industrial Fieldbus Systems
Provides high common-mode transient immunity of 100kV/us to ensure data integrity in noisy industrial environments.
Multi-Channel Logic Level Shifting
The 1.8V to 5V supply range allows for seamless level translation between different logic domains in the same system.

Getting Started

To evaluate this part, use the EVAL-ADUM16xEBZ evaluation board which provides access to all six channels via test points and screw terminals. Ensure that VDD1 and VDD2 are decoupled with 0.1uF ceramic capacitors placed as close to the pins as possible. Design your PCB layout to respect the creepage and clearance requirements for 3000Vrms isolation.

Also Consider

ISO7761 TITexas Instruments - Provides a similar 5/1 channel configuration with a higher 5000Vrms isolation rating in a SSOP-16 package.
