ADM3485ARZ

Overview

The ADM3485ARZ is a 3.3V low power, differential line transceiver designed for balanced data transmission in RS-485 and RS-422 networks. It operates at data rates up to 10Mbps and features a half-duplex configuration in a compact 8-SOIC package.

Why Choose This Part

This transceiver includes a low-power shutdown mode consuming only 2nA and features thermal shutdown protection to prevent output contention damage. It supports a wide common-mode input range from -7.5V to 12.5V, ensuring reliable data recovery in electrically noisy environments.

Applications

Getting Started

When designing with the ADM3485ARZ, place a 0.1uF decoupling capacitor close to the VCC pin and ensure proper bus termination with 120-ohm resistors at both ends of the network. Evaluation can be performed using the Analog Devices EVAL-RS485HDEBZ board or by integrating the SOIC-8 footprint into a custom prototype PCB.
