Overview
The AD9832BRU-REEL, produced by Analog Devices Inc., is a numerically controlled oscillator (NCO) that integrates a phase accumulator, a sine look-up table, and a 10-bit digital-to-analog converter (DAC) on a single CMOS chip. This Direct Digital Synthesis (DDS) chip is designed to generate high-quality sine waves and supports various modulation schemes, including frequency and phase modulation. The device operates with a clock rate up to 25 MHz and offers high frequency accuracy, controlled to one part in 4 billion. It is available in a 16-lead TSSOP package and is suitable for a wide range of applications requiring precise signal generation and modulation.
