ADIADuM5401ARWZ
Overview
The ADuM5401ARWZ is a quad-channel digital isolator based on Analog Devices' iCoupler technology, featuring integrated isoPower dc-to-dc conversion. It provides 2500Vrms isolation and eliminates the need for a separate isolated dc-to-dc converter in low-power designs by providing up to 500mW of isolated power from a 3V to 5.5V supply. This specific variant offers three forward channels and one reverse channel with a 1Mbps data rate.
Why Choose This Part
The primary advantage is the integration of both signal and power isolation in a single 16-SOIC package, significantly reducing PCB area and BOM complexity. It features a high common-mode transient immunity (CMTI) of 25kV/us and maintains isolation integrity across an operating temperature range of -40C to +105C.
Applications
Key Specifications
Getting Started
When designing with the ADuM5401ARWZ, ensure proper bypass capacitors (0.1uF and 10uF) are placed as close to the VDD and VISO pins as possible to manage switching noise from the internal dc-to-dc converter. Use a four-layer PCB with internal ground planes to minimize EMI emissions associated with the integrated power technology. Engineers can evaluate this technology using the EVAL-ADuM5401EBZ evaluation board.
