Product Introduction

Overview

The AD7391ARZ-REEL is a 10-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the AD7390/AD7391 family, known for their low power consumption and single-supply operation. The AD7391 is designed to operate from a single 3V supply, making it ideal for battery-operated and power-sensitive applications. It features a serial-input interface compatible with SPI and QSPI, and it includes a voltage-switched, laser-trimmed DAC, rail-to-rail output op amps, and a separate serial-input register and DAC register.
