Product Introduction

Overview

The AD9834BRUZ-REEL, produced by Analog Devices Inc., is a 75 MHz low power Direct Digital Synthesizer (DDS) device. It is designed to generate high-performance sine and triangular wave outputs, making it an ideal component for various applications requiring precise waveform generation. The device also features an on-board comparator, enabling the production of a square wave for clock generation. With a power consumption of only 20 mW at 3 V, it is particularly suited for power-sensitive applications.
