ADIMAX14931EASE+

Overview

The MAX14931EASE+ is a four-channel digital isolator providing 2750Vrms of galvanic isolation between circuits using capacitive coupling technology. This specific variant features a 3/1 channel configuration (three forward, one reverse) and supports data rates up to 25Mbps. It serves as an integrated level translator and isolator, operating across a wide supply voltage range from 1.71V to 5.5V.

Why Choose This Part

The device features a high Common Mode Transient Immunity (CMTI) of 25kV/us (typical), ensuring robust data transmission in high-noise environments. Its wide supply range down to 1.71V allows for direct interfacing with modern low-voltage FPGAs and MCUs without external level shifters. Furthermore, it maintains low power consumption, drawing only 2mA at 12.5MHz when operating at 3.3V.

Applications

Getting Started

To evaluate this part, designers can use the MAX1493XEVKIT evaluation kit, which provides a pre-laid-out PCB to test isolation and timing characteristics. When designing your own PCB, ensure a minimum creepage and clearance is maintained under the 16-SOIC package to meet your specific safety standards. Place 0.1uF bypass capacitors as close as possible to the VDDA and VDDB pins on both sides of the isolation barrier.
