Product Introduction

Overview

The AD5320BRM-REEL7 is a single, 12-bit buffered voltage output digital-to-analog converter (DAC) produced by Analog Devices Inc. This component operates from a single supply voltage ranging from 2.7 V to 5.5 V and consumes a low current of 115 μA at 3 V. It features an on-chip precision output amplifier that enables rail-to-rail output swing, making it suitable for a wide range of applications, particularly in portable, battery-operated equipment.

Key Features

  • Rail-to-Rail Output: The AD5320 features an on-chip precision output amplifier that allows for rail-to-rail output swing, ensuring the widest dynamic output range.
  • Low Power Consumption: The device consumes only 115 μA at 3 V and reduces to 1 μW in power-down mode, making it ideal for battery-operated equipment.
  • Power-On Reset: The DAC output powers up to zero volts and remains there until a valid write takes place to the device.
  • Power-Down Feature: The device can be put into power-down mode over the serial interface, reducing current consumption significantly.
  • Versatile Serial Interface: Compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards, operating at clock rates up to 30 MHz.
  • Software Selectable Output Loads: In power-down mode, the output loads can be software selected.

Applications

  • Portable Battery-Powered Instruments: Ideal for devices that require low power consumption and high precision.
  • Digital Gain and Offset Adjustment: Suitable for applications requiring precise gain and offset adjustments.
  • Programmable Voltage and Current Sources: Can be used in systems that need programmable voltage or current outputs.
  • Programmable Attenuators: Useful in applications requiring adjustable attenuation levels.
