ADIMAX14432FASE+
Overview
The MAX14432FASE+ is a high-speed, four-channel digital isolator providing 3750Vrms galvanic isolation using capacitive coupling technology. It supports data rates up to 200Mbps with extremely high common-mode transient immunity (CMTI) of 50kV/us typical, ensuring signal integrity in electrically noisy environments. This specific variant features a default-low output state and operates across a wide supply range of 1.71V to 5.5V.
Why Choose This Part
This isolator offers a high data-to-power efficiency ratio with low power consumption across its entire 1.71V to 5.5V voltage range. Its 200Mbps throughput and 50kV/us CMTI make it suitable for high-speed switching applications where robust noise rejection is critical. The narrow 16-SOIC package provides a compact footprint while maintaining 3750Vrms isolation safety standards.
Applications
Key Specifications
Getting Started
To evaluate this component, use the MAX14432FWEVKIT evaluation kit which provides a pre-mounted IC and SMA connectors for signal integrity testing. Ensure that VDD1 and VDD2 are decoupled with 0.1uF ceramic capacitors placed as close to the device pins as possible. Design the PCB layout with a clear isolation gap beneath the 16-SOIC package to maintain the rated creepage and clearance distances.
