Product Introduction

Overview

The ADM1490EBRZ-REEL7, produced by Analog Devices Inc., is a high-performance RS-485/RS-422 transceiver designed for balanced data transmission. This device is part of the ADM1490E/ADM1491E series and is optimized for use in applications requiring reliable and high-speed data communication. It operates from a single 5 V power supply and is compliant with TIA/EIA-485-A-98 and TIA/EIA-422-B standards. The transceiver features a differential line driver and a differential line receiver, making it suitable for full-duplex data transmission.

Key Features

  • Compliance with TIA/EIA-485-A-98 and TIA/EIA-422-B standards for reliable data transmission.
  • Differential line driver and receiver for balanced data transmission.
  • Single 5 V power supply operation with ±5% tolerance.
  • High-speed data transmission up to 16 Mbps.
  • Low propagation delay and skew to ensure high baud rate operation.
  • Short-circuit protection and thermal shutdown to prevent excessive power dissipation.
  • Electrostatic discharge protection up to ±8 kV using the human body model (HBM).
  • Fail-safe receiver feature that results in a logic high output state if inputs are unconnected.

Applications

  • Motor control systems requiring high-speed data communication.
  • Industrial automation and control systems where reliable data transmission is critical.
  • Point-of-sale terminals and other commercial equipment needing robust serial communication.
  • Medical devices and diagnostic equipment that require precise and reliable data transmission.
  • Telecommunications and networking equipment for reliable serial communication.
