Product Introduction

Overview

The ADM3311EACPZ-REEL, produced by Analog Devices Inc., is a ruggedized RS-232 line driver/receiver integrated circuit. This device is designed to fully meet the EIA-232 standard while operating from a single power supply of 2.7 V to 3.6 V. It features an on-board charge pump dc-to-dc converter, eliminating the need for dual power supplies. The ADM3311E is particularly suited for battery-powered portable devices and harsh electrical environments due to its low power consumption and robust ESD protection.

Key Features

  • Low Power Consumption: The device operates in Green Idle mode, minimizing power consumption by gating the charge pump oscillator on and off to maintain the output voltage under varying load conditions.
  • High Transmission Rates: Supports data rates up to 460 kbps.
  • ESD Protection: Offers ESD protection up to ±15 kV on RS-232 and CMOS I/O lines.
  • Shutdown Facility: A shutdown feature reduces power consumption to less than 1 µA, with one receiver remaining active to monitor peripheral devices.
  • Single Supply Operation: Operates from a single 2.7 V to 3.6 V power supply, eliminating the need for dual power supplies.
  • Robust Design: Includes overvoltage protection and latch-up immunity, making it suitable for harsh electrical environments.

Applications

  • Mobile phone handsets and data cables
  • Laptop and notebook computers
  • Printers and peripherals
  • Modems
  • PDAs, hand-held devices, and palmtop computers
  • Automotive applications
