Product Introduction

Overview

The AD5321BRM-REEL7 is a 12-bit, voltage-output digital-to-analog converter (DAC) produced by Analog Devices Inc. This device operates from a single supply voltage ranging from 2.5 V to 5.5 V and consumes a low current of 120 μA at 3 V. It features a 2-wire (I2C-compatible) serial interface, allowing for easy communication and control. The AD5321 is part of a family of DACs that include the AD5301 and AD5311, offering different resolutions but similar functionalities.

Key Features

  • Rail-to-Rail Output Swing: The on-chip output amplifier allows for rail-to-rail output swing, enhancing the device's versatility in various applications.
  • Low Power Consumption: The device consumes a low current of 120 μA at 3 V, making it suitable for battery-operated and power-sensitive applications.
  • 2-Wire Serial Interface: The I2C-compatible serial interface supports clock rates up to 400 kHz and allows multiple devices to share the same bus.
  • Programmable Power-Down Modes: The DAC can be turned off completely or the output can be pulled low by an on-chip resistor, reducing power consumption in idle states.
  • Power-On Reset: Ensures the DAC powers up in a defined state, with the DAC register filled with zeros until a valid write sequence is made.

Applications

  • Portable Battery-Operated Equipment: The low power consumption makes it ideal for devices such as handheld instruments and portable medical devices.
  • Industrial Control Systems: Suitable for use in control systems where precise analog output is required.
  • Automotive Systems: Can be used in automotive applications due to its robust temperature range and reliability.
  • Medical Devices: Applicable in medical equipment where accurate and stable analog outputs are crucial.
