Product Introduction

Overview

The ADM488AN, produced by Analog Devices Inc., is a low-power, full-duplex differential line transceiver designed for communication on multipoint bus transmission lines. It complies with both EIA RS-485 and RS-422 standards, making it suitable for balanced data transmission. The device operates from a single 5 V ± 10% power supply and is fabricated using BiCMOS technology, combining low power CMOS with fast switching bipolar technology. This transceiver is ideal for applications requiring robust and reliable data transmission in electrically harsh environments.
