ADIMAX14850AEE+

Overview

The MAX14850AEE+ is a six-channel digital isolator designed to provide 600Vrms of galvanic isolation in a compact 16-pin QSOP package. It features a versatile channel configuration including two bidirectional channels for I2C and four unidirectional channels for SPI, UART, or RS-485 control signals. This device is optimized for high-speed operation with data rates up to 50Mbps on unidirectional channels while maintaining low power consumption across a 3V to 5.5V supply range.

Why Choose This Part

The integration of both bidirectional and unidirectional channels in a single 16-QSOP package significantly reduces PCB footprint compared to using discrete optocouplers or multiple isolator ICs. It offers high common-mode transient immunity (CMTI) of 1.5kV/us and operates over an extended temperature range of -40C to +125C, ensuring reliable performance in harsh industrial environments.

Applications

Getting Started

To evaluate this device, use the MAX14850EVKIT for rapid prototyping of isolated I2C and SPI interfaces. Ensure that bypass capacitors (0.1uF) are placed as close as possible to the VDD1 and VDD2 pins on both sides of the isolation barrier to maintain signal integrity at high data rates. Refer to the datasheet layout guidelines to maintain the required creepage and clearance distances for 600Vrms isolation.
