Product Introduction

Overview

The AD5666BRUZ-2, produced by Analog Devices Inc., is a quad, 16-bit, buffered voltage-output Digital-to-Analog Converter (DAC). This component operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. It features an on-chip reference with an internal gain of 2, providing high precision and stability. The AD5666BRUZ-2 is particularly notable for its low power consumption and versatile interface capabilities, making it suitable for a wide range of applications requiring precise analog output.
