Overview
The AD9835BRUZ-REEL, produced by Analog Devices Inc., is a highly integrated direct digital synthesis (DDS) chip. This component employs a phase accumulator, a COS lookup table, and a 10-bit digital-to-analog converter (DAC) on a single CMOS chip. It is designed to generate high-quality sine waves and offers advanced modulation capabilities, including phase and frequency modulation. The AD9835 is particularly useful in applications requiring precise frequency generation and control, such as RF communications, test equipment, and sensory systems.
