Product Introduction

Overview

The ADM232AANZ is a high-speed RS-232 line driver/receiver integrated circuit produced by Analog Devices Inc. This device is part of the ADM222, ADM232A, and ADM242 family, known for their high transmission rates and efficient power management. The ADM232AANZ operates from a single 5 V power supply and is designed to meet all EIA-232-E and V.28 specifications. It features two RS-232 drivers and two RS-232 receivers, making it suitable for a variety of serial communication applications.

Q & A

  1. What is the transmission rate of the ADM232AANZ?
    The transmission rate of the ADM232AANZ is up to 200 kB/s.
  2. What type of power supply does the ADM232AANZ require?
    The ADM232AANZ operates from a single 5 V power supply.
  3. How many RS-232 drivers and receivers does the ADM232AANZ have?
    The ADM232AANZ has two RS-232 drivers and two RS-232 receivers.
  4. Does the ADM232AANZ meet industry standards for RS-232 communication?
    Yes, the ADM232AANZ meets all EIA-232-E and V.28 specifications.
  5. What technology is used in the ADM232AANZ?
    The ADM232AANZ uses BiCMOS technology, combining low power CMOS with high-speed bipolar circuitry.
  6. What is the purpose of the shutdown function in the ADM232AANZ?
    The shutdown function reduces the supply current to a very low level (0.1 µA for ADM222), disabling the device to conserve power.
  7. What packages is the ADM232AANZ available in?
    The ADM232AANZ is available in 16-lead DIP and surface-mount (SOIC) packages.
  8. How does the ADM232AANZ handle receiver outputs during shutdown?
    During shutdown, the receivers continue to operate normally unless disabled using the enable function (for ADM242).
  9. What are the typical applications of the ADM232AANZ?
    The ADM232AANZ is used in industrial automation, medical devices, point-of-sale terminals, embedded systems, and other applications requiring high-speed RS-232 communication.
  10. What is the role of the charge pump in the ADM232AANZ?
    The charge pump generates ±10 V from the 5 V input supply using small external capacitors, allowing the device to produce RS-232 bipolar levels.
