Product Introduction

Overview

The AD7391ARUZ-REEL is a 10-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. This device is part of the AD7390/AD7391 family, which includes pin-compatible 10-bit and 12-bit DACs. The AD7391 is designed for single-supply operation and is built using a CBCMOS process, offering low cost and ease of use in 3 V systems. It is particularly suited for battery-operated applications due to its low power consumption of less than 100 µA over a supply voltage range of 2.7 V to 5.5 V.

Key Features

  • Single-Supply Operation: The AD7391 operates from a single supply voltage between 2.7 V and 5.5 V, making it suitable for battery-operated devices.
  • Low Power Consumption: Consumes less than 100 µA, ideal for power-sensitive applications.
  • High-Speed Serial Interface: Compatible with SPI and QSPI serial interfaces, with a 3-wire interface consisting of serial data input (SDI), clock (CLK), and load (LD) pins.
  • Rail-to-Rail Output: The output voltage range can be set from 0 to VDD, allowing for full-scale voltage output equal to the positive supply voltage or any value in between.
  • Doubled-Buffered Serial-Data Interface: Allows preloading of a new data value into the serial register without disturbing the present DAC values.
  • CLR Pin for Reset: Available to reset the DAC register to zero-scale, useful for power-on reset or system failure recovery.

Applications

  • Automotive Systems: Suitable for automotive applications due to its robust performance over a wide temperature range.
  • Portable Communications: Ideal for portable communication devices due to its low power consumption and compact design.
  • Digitally Controlled Calibration: Used in applications requiring precise digital control over analog outputs, such as calibration systems.
  • Battery-Operated Devices: Suitable for any battery-operated device requiring high precision and low power consumption.
